Question

A rectangle has perimeter 80 m and length 27 m. What is the width?

Answer 1

take 27 + 27 then subtract that from 80 then divide by 2 and that will equal the width 

Answer 2

There are 2 lengths and 2 widths in a rectangle

the length is 27 

27 x 2 = 54

80 - 54 = 26

26/2 = 13

13 is your answer for the width

hope this helps
