Question

A rectangle with a perimeter of 102cm has a length that is 5 times the width. What is the length and witdh

Answer 1

Thank you so much for your help!

Answer 2

Use L for length and W for width, then:
Length is 5 times width: L = 5W
The perimeter of a rectangle is L + L + W + W or 2L + 2W
We are told the perimeter is 102 cm, so
2L + 2W = 102, but L = 5W, so
2(5W) + 2W = 102
Now you have an equation with only one variable, W, so you can solve it.
Once you know what W is, then L = 5W will give you L.
