Question

If the dimensions of a room are 10 ft by 20 ft, what is its approximate area in square meters?

Answer 1

Area = length x width
= 10 ft x 20 ft
Since 1 ft = 0.3048 m, 10 ft = 3.048 m and 20 ft = 6.096 m:
= 3.048 m x 6.096 m
= 18.58 m²

The answer is  d. 18.58, or 19 m2

Answer 2

10ft times 20 ft is 200 ft.

200 ft is 18.58 m^2, so the answer is D.
