Question

Shelly is hanging strings of holiday lights around the front windows of her house. Each window is a square with sides measuring 5 feet in length. She has a total of 80 feet of light strings. How many windows will she be able to decorate?

Answer 1

Answer:

  4

Step-by-step explanation:

The perimeter of each square window is 4 times the length of one side, so is 20 feet.

80 feet can be divided into 80/20 = 4 sections of 20 feet each.

Shelly has enough lights to surround 4 windows.

Answer 2

The right answer is 4
