The width of backyard is 45 feet.

Step-by-step explanation:

Given,

Length of backyard = 120 feet

Perimeter of backyard = 330 feet

Width of backyard = w

Perimeter = 2(Length + Width)

$330=2(120+w)\\330=240+2w\\330-240=2w\\90=2w\\2w=90$

Dividing both sides by 2

$\frac{2w}{2}=\frac{90}{2}\\w=45$

The width of backyard is 45 feet.
