Question

The length is :____ meters and the width is ____meters.

Answer 1

Length= 8, Width= 4

Explanation:

Say the length is l, and the width is w.

We can set l, the length as 2w, as it is double the length.

The perimeter= 2l + 2w= 24

Input l as 2w, get

4w+2w=24

6w=24, w=4.

Length is w*2, so length is 8.
