The length of a rectangle is 2 centimeters longer than its width, if the perimeter of the rectangle is 60cm, find its width and length?

Let the width of rectangle = x centimeter

According to condition length = (x+2) centimeter

As accoding to formula

perimeter of rectangle = 2 (lenght + width)

so Perimeter = 2{ (x+2) + (x) } equation 1

Give perimeter = 60cm equation 2

comparing equation 1 and equation 2

2{ (x+2) + (x) } = 60

Solving 2{2x+2} = 60

4x+4 = 60

subtracting 4 both sides

4x = 56

dividing 4 both sides.

x=14 width of rectangle

AS we have assume length = x+2 ⇒ 14 + 2

Length = 16
