Question

Jorge's rectangular garden was 17 feet long and had a perimeter of 54 feet. He made his garden 5 feet longer. What is the area of his new garden?

Answer 1

If I remember correctly, the perimeter of a rectangle is \(P=2l+2w\) and you have 17 ft for length.

So you can solve it: \(\large 54=2(17)+2w\)

\(54=34+2w\)
\(20=2w\)
\(10=w\)

And the length got extended 5 more feet. 17+5=22

\(\large A=l*w\)

\(\large A=22*10\)

That should be it :)
