Because base times height = the area of a parallelogram and a triangle's area

is half that of the parallelogram that the triangle exactly fits into.

## Related Questions The relationship between the area of a triangle and a rectangle is a Triangle is base times height divided by 2. Area of a rectangle is length times height.  Typically this formula is used to find the area of a triangle. The area of any triangle has the same formula, which is base times height, divided by 2. A scalene triangle is a triangle with three sides of unequal length, which is not important when calculating the area. Area = (length) times (width)Length = (area) divided by (width)Width = (area) divided by (length) Because a triangle is half of a rectangle. The area of a rectangle is length times width, the area of a triangle is half that. the formula for the area of a triangle is: base times height divided by two. the area of a triangle is base times height times one half and rectangle is length times width Sorry no. Further answer It's area divided by length.     The formula for the surface area of a circle is pi times the square of the radius. The formula for the surface area of a triangle is base times height, divided by 2. The formula for the surface area of a square or rectangle is length times width. The equation for surface area of a square or rectangle is length times width. The equation for surface area of a triangle is base times height, divided by 2. The equation for surface area of a circle is pi times the square of the radius. For a rectangle: length times width For a triangle: length times width divided by two For a circle: pie times radius squared For a rectangular prisim: length times width times height For a sphere: four thirds pie times radius cubed in finding the area if a square or rectangle multiply the length and width, for a triangle, multiply length and width divided by two. The answer is base times height divided by two or half base times height It's b x h divided by 2 It is the bottom of the triangle, times the height of the triangle (length from highest part, to lowest part) and then divide that number by 2. _______________________________________________________________ Base x Height x 0.5  It can be divided into 5 equal triangles so find the area of a triangle and then times it by 5. Area of a triangle is 0.5 times base times perpendicular height. 0.4330 times the length of a side (in square units of length) The area of a right triangle is dependent on the length of leg A and leg B. The formula for this is A= leg a multiplied by leg b then divided by 2. for square and rectangle it's length times width for a circle it's 3.14 times radius squared for triangle it'slenth height into base divided by 2  ###### Math and ArithmeticGeometrySchool SubjectsUnits of MeasureAlgebra Copyright © 2020 Multiply Media, LLC.
