Answer:
a. To the nearest whole inch:
To find the length of one side of the square frame, we need to take the square root of the area. So:
√(55) ≈ 7.4
Rounding 7.4 to the nearest whole inch, we get 7 inches. Therefore, the length of one side of the frame is 7 inches.
b. To the nearest tenth of an inch:
Again, we take the square root of the area:
√(55) ≈ 7.4161984
Rounding 7.4161984 to the nearest tenth of an inch, we get 7.4 inches. Therefore, the length of one side of the frame is 7.4 inches.
