Asked by Annika
A rectangular lawn is 60meters by 80meters. A part of the lawn is torn out to install a pool, leaving a strip of lawn of uniform width around the pool. The area of the poolnis 1/6 of the old lawn area. How wide is the strip of lawn?

If the strip has width w, the pool is
60-2w by 80-2w
So,
(60-2w)(80-2w) = 1/6 (60)(80)
Now just solve for w.
60-2w by 80-2w
So,
(60-2w)(80-2w) = 1/6 (60)(80)
Now just solve for w.
