# 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?

Lea needs $8$ more feet of fencing.

#### Explanation:

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

$P = 2 \left(14 + 15\right)$

$P = 2 \left(29\right)$

$P = 58$

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

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