The area of the rectangle is 243 sq.cm.
The perimeter of a Rectangle is equal to 2( Length + Width).
The length of a rectangle is 3 times the width
Let the width of the rectangle is x cm
The length of the rectangle will be 3x cm
The Perimeter of a rectangle is 72 cm.
From the formula of Perimeter of a Rectangle
72 = 2 ( x +3x )
36 = 4x
x = 9 cm
Width = 9cm
Length = 3 *9 = 27 cm
Area of Rectangle = Length * Width
Area of Rectangle = 9 *27 = 243 sq.cm
Therefore, the area of the rectangle is 243 sq.cm.
