Question

Ms. Hanna measured her bedroom and it measured 3 feet 2 inches long on one side. She then measured the living room and it measured 30 inches long. Which room is longer? Please use dimensional analysis

Answer 1

Let's convert the bedroom measurement into inches.

3 ft 2 in = 3 ft + 2 in

3 ft * (12 in)/(1 ft) + 2 in = 36 in + 2 in = 38 in

38 in > 30 in

The bedroom is longer.
