Question

Lea wants to put a fence around her garden. Her garden measures 14 feet by 15 feet. She has 50 feet of fencing. How many more feet of fencing does Lea need to put a fence around her garden?

Answer 1

Lea needs `8` more feet of fencing.

Explanation:

Presuming the garden to be rectangular, we can find out the perimeter by the formula `P=2(l+b)`, where P=Perimeter, l=length and b=breadth.

`P=2(14+15)`

`P=2(29)`

`P=58`

Since the perimeter is `58` feet and Lea has `50` feet of fencing, she will need:

`58-50=8` more feet of fencing.
