Question

A rectangle has perimeter 88 cm and length 38 cm. What is its width?

Answer 1

`color(blue)(6cm)`

Explanation:

Let the unknown width be `x`:

The perimeter is the sum of all the sides.

`38+38+x+x`

This equals 88cm.

`:.`

`38+38+x+x=88`

`2x=88-38-38=12`

`x=12/2=6`

The width is `6`cm
