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! :)
