Avi’s dining room measures 124 square feet and is in the shape of a square. Which is the best estimate of the length of one side of the room, to the nearest tenth of a foot?

Question

10.7 feet
10.9 feet
11.1 feet
11.4 feet

Answer 1

Since the dining room is in the shape of a square, the length of one side can be found by taking the square root of the total square footage.

√124 = 11.1355

Rounded to the nearest tenth, the best estimate of the length of one side of the room is 11.1 feet.

Therefore, the answer is 11.1 feet.
