Rectangle has 4 sides

You have the 2 side lengths (l) and the 2 side widths (w)

"The length is 20 centimeters more than triple the width" in math terms is

l = 20 + 3w

The perimeter is 96 centimeters, which is all the sides added up

2l + 2w = 96

2(20 + 3w) + 2w = 96

40 + 6w + 2w = 96

40 + 8w = 96

8w = 56

w = 7


now plug in w = 7 to get length in

l = 20 + 3w
