in order to find area of rectangle=(len*bred)
Area of a rectangle: a = l * w
A = lw Area of a rectangle = length times width
L.A.= 2*pi*radius*height its not like finding the area of a rectangle. a cylinder is a 3-D shape and a rectangle is a flat shape
Area of rectangle is l x b. Where l is length and b is breath of the rectangle.
the area of a triangle is base times height times one half and rectangle is length times width
By finding the total area, you can see if all of the areas of your shapes combined match the total area of the rectangle. It's a safe-check.
base times height = area
Squares are rectangles so the formula for area will stay the same.
I beleve that is the formula for finding the area of a rectangle or squareLength*Width equals area for rectangles. LxW=Area of a rectangle.
Multiply the base by the height !
Length times width.
The answer depends on what information you have about the rectangle: the area and width, or width and diagonal, area and perimeter or some other measures.
