30 square feet
if a rectangle has width of 5 and diagonal with lenght of 13, what is the area of the rectangle? Use Pythagoras' theorem to find the length of the rectangle which will be 12 5*12 = 60 square units
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.
Area of a square/rectangle=its length × its width
Area of a rectangle in square units = length*width
To find the area of a rectangle, multiply the length times the width. The result will be in square inches.
For a rectangle or square, Area = Length * Width So Length = Area / Width.
36 square inches is the area.
Area= Length multiplied by Width
Area= Length multiplied by Width

In the formula for the rectangle, put the width equal to the length.
Multiply the long side of the rectangle's length by itself.
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.
To find the area of a square or a rectangle, you have to do the length times the width.
Surface area = length*width in square units
