Length X Width.
The area formula for the parallelogram is related to the area formula for a rectangle because you can make the parallelogram into a rectangle to find the area.
The formula to find the area of a rectangle is: A = (length)(width)
Yes, LxW=Area. For Surface Area, add up the area of all the sides
If the base is a rectangle, use the formula for the area of a rectangle.
It depends on the size of the triangular prism, but depending on the side of the prism you use the triangle area formula to find it or the rectangle area formula to find it.
Its surface area.
In the formula for the rectangle, put the width equal to the length.
The area of a rectangle is bh. b is base, and h is height.
Surface area = length*width in square units
A traingle covers half the area of a rectangle with the same base and [perpendicular] height.
The formula of the rectangle is multiplying the length and the width to get the area. You can add all the four sides so as to find the perimeter of the rectangle.
of course base times height for a square or rectangle. but for a trapezoid a= h x "b1+b2"
The formula for a rectangle is height x width (A=ab)Since you said surface area, I'm pretty sure that you might mean a rectangular prism. To get this, you would need to find the area of each "rectangle side". To do this, you use the first formula, using height (a), width (b), and depth (c). The formula for theSurface Area of a Rectangular Prism = 2ab + 2bc + 2ac
rectangle and octahedron
The formula for the area of a square is simply L2 (sometimes referred to as s2 ) where L (s) is the length of one side. The formula for the area of a rectangle is LW, where L is the length and W is the width. The formula for the area of a rectangle can be used to find the area of a square, but the formula for the area of a square cannot be used to find the area of a rectangle. This is because by definition, all squares are rectangles, but not all rectangles are squares.
length times width
area divides by length
The formula to find the surface area of a parallelogram is Base*Height.
Rectangle Surface Area: L X W X 6 (the number of sides)
You find the area of each face and add the results together.
Multiply the length x the width.
Base times height
In order to find the area of a rectangle, you must follow the formula A= l x w where A is area, l is length, and w is width.
Surface area = 4*Pi*radius2
well finding the surface area of one face is just like finding the area of a flat rectangle, so all you have to do is find the area of each face and add them up into one sum. i believe that the formula is 2ab + 2bc + 2ac
