The length of a rectangle is 2 centimeters longer than its width. The perimeter is 16 centimeters.
Length of rectangle = L
Width of the rectangle = W
The length of a rectangle is 2 centimeters longer than its width.
So L = W + 2
Perimeter of rectangle = 2* length + 2* width

Given perimeter = 16cm

Subtract 4 on both sides
12 = 4W
Divide by 4 on both sides
3 = W
So width of the rectangle = 3 cm
Length = W + 2 = 3+2 = 5 cm
