# How do you find the area of a parallelogram without given height?

012 ###### 2016-05-15 10:03:54

If you have the lengths of the two sides and a diagonal, then you can use Heron's formula to find the area of one triangle and double it for the area of the parallelogram.

If you have two sides and an angle, then area = a*b*sin(C).

## Related Questions  Not too sure of the given dimensions but the area of a parallelogram is length times perpendicular height. You can find the height of a parallelogram given the area and base measures by working backwards from the area formula. The area of a parallelogram is found with the formula: Area = Base * Height To solve this equation for Height, we divide both sides by the base. Area / Base = (Base * Height) / Base Simplify: Area / Base = Height Too many dimensions have been given because the area of a parallelogram is length times perpendicular height.  That will depend on the length of its base which has not been given.  To find the area of a parallelogram, multiply the base by the height. The formula for area of a parallelogram is the base times the height (BXH=Area). It depends upon the shape. For example, if it is a parallelogram, then divide the area by the height to get the base. The parallelogram has twice the area of the triangle if their bases are the same and their heights are the same. Area triangle = 1/2 base x height. Area parallelogram = base x height. To find the area of a parallelogram, multiply the length of the base by the height. The height should be perpendicular to the base. The formula for area of a parallelogram is bh. Base times height.  Area of a triangle = 0.5*base*perpendicular height Area of a parallelogram = base*perpendicular height The area of a parallelogram is the base times the height; the height must be measured perpendicular to the base. If you correctly measure the height perpendicular to the base and you get different measurements, then you are NOT dealing with a parallelogram. Area of a parallelogram = base * height = 6.5 * 1.5 = 9.75 square units. Parallelogram = Base*Height Triangle = 0.5*Base*HeightParallelogram = Base*Height Triangle = 0.5*Base*HeightParallelogram = Base*Height Triangle = 0.5*Base*HeightParallelogram = Base*Height Triangle = 0.5*Base*Height The area of a parallelogram is base times perpendicular height With the dimensions given the perpendicular height of the rectangle will be greater than the parallelogram. Therefore the rectangle will have a greater area than the parallelogram. A parallelogram has a base of 12 meters and a height of 1.5 meters. What is its area? The area of a polygon is the number of square units inside the polygon. Area is 2-dimensional like a carpet or an area rug. A parallelogram is a 4-sided shape formed by two pairs of parallel lines. Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: where is the base, is the height, and &middot; means multiply. The base and height of a parallelogram must be perpendicular. However, the lateral sides of a parallelogram are not perpendicular to the base. Thus, a dotted line is drawn to represent the height.Example 1: Find the area of a parallelogram with a base of 12 centimeters and a height of 5 centimeters. Solution: = (12 cm) &middot; (5 cm) = 60 cm2 ---- Example 2: Find the area of a parallelogram with a base of 7 inches and a height of 10 inches. Solution: = (7 in) &middot; (10 in) = 70 in2 ---- Example 3: The area of a parallelogram is 24 square centimeters and the base is 4 centimeters. Find the height. Solution: 24 cm2 = (4 cm) &middot; 24 cm2 &divide; (4 cm) = = 6 cm ---- Summary: Given the base and height of a parallelogram, we can find the area. Given the area of a parallelogram and either the base or the height, we can find the missing dimension. The formula for area of a parallelogram is: where is the base, is the height, and &middot; means multiply."1+1 =?""Have Fun" The formula to find the surface area of a parallelogram is Base*Height.  The area of a parallelogram is base x height and the area of a triangle is 1/2 x base x height. So the area of a parallelogram will always be 2 times bigger than a triangle with the same base and height. The rule for finding the area of a parallelogram is a simple equation of A=bh. For this equation, the A is area, b is base, and h is height. The area of a parallelogram is equal to the shape's base multiplied by the shape's height.
