If the base is a rectangle, use the formula for the area of a rectangle.
In the formula for the rectangle, put the width equal to the length.
A traingle covers half the area of a rectangle with the same base and [perpendicular] height.
of course base times height for a square or rectangle. but for a trapezoid a= h x "b1+b2"
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.
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.
If the base is a rectangle, use the formula for the area of a rectangle.

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
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.
Area of what? Every geometrical shape has a different formula to find its area. The simplest one: to find the area of a rectangle whose edge lengths are h and w, area = h*w.
Area of a rectangle= length x height.For example:A 2' by 4' rectangle would have an area of 2 x 4 = 8 square feet.As a formula, it is L*W=A.
You take the formula for a rectangle, replace what you know, and solve for the remaining variable.
