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
