Hi!

To find the perimeter of a rectangle, use this formula.

(w = width

l = length

p = perimeter)

w + w + l + l = p

Put in the values we already have.

55 + 55 + l + l = 226

Simplify.

110 + 2l = 226

Subtract 110 from both sides.

110 - 110 + 2l = 226 - 110

2l = 116

Divide by 2 on both sides.

2l/2 = 116/2

l = 58

The rectangle's length is 58 centimeters.

Hope this helps! :)
