Answer:

The perimeter is 1280ft

Explanation:

Let the side length of the square be s.

Then the distance around three sides is 3s.

According to the question the distance around 3 sides of a square city block is 960 feet.

This implies that:

3s = 960

s = (960)/(3)

s = 320

The perimeter of a square is

p = 4s

Substitute s=320 to get:

p = 4(320)

p = 1280

The perimeter is 1280 ft
