length times width
Area of a rectangle = (length of the rectangle) multiplied by (width of the rectangle)
Area of a rectangle: a = l * w
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
in order to find area of rectangle=(len*bred)
base times height = area
Squares are rectangles so the formula for area will stay the same.
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.
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 !
