Indira was measuring the length of her school's hallway. The first part of the hallway was 132 inches long. The next part was 3 yards long. How long is the hallway in
feet?

20 ft

Step-by-step explanation:

12 inches = 1 foot

12 : 1 = 132 : y

12 × y = 132 × 1

12y = 132

12y ÷ 12 = 132 ÷ 12

y = 11

11 ft

1 yard = 3 feet

1 : 3 = 3 : y

1 × y = 3 × 3

1y = 9

y = 9

9 ft

11 ft + 9ft = 20 ft
