Question

A rectangle has perimeter 88cm and length 35cm. What is the width? ​

Answer 1

Answer:
9cm

Explanation:
A rectangle has two sets of two equal sides. Using this, you can double 35 to get 70 and that is the sum of 2 sides.
Since the entire perimeter is 88, that leaves the rest of the total to be 18.
If you divide 18 by 2 (since there are 2 sides), you get 9. That is the width! Hope this helps.
