A rectangular room is twice as long as it is wide, and its perimeter is 60 meters. Find the dimensions of the

room.
The length is __
meters and the width is __
meters.

Answer 1

Answer: 20, 10

Explanation:

Let the width be w. Then, the length is 2w. Substituting into the formula for the perimeter of a rectangle,

`2(w+2w)=60\\\\w+2w=30\\\\3w=30\\\\w=10\\\\\implies 2w=2(10)=20`
