You multiply the width by the length to get the area. In this case the answer would be 200 square feet.
10 ft x 20 ft room = 200 square feet
200 square feet
200 square feet
18.58 square meters.
To find the area (square feet) of a room, multiply the length by the width. 10 feet x 20 feet = 200 square feet.
20 feet x 10 feet = 200 square feet
= 20 sq feet
The area of 20 feet times 10 feet = 200 square feet.
200 square feet

The answer depends on the units used for 10 and 20. Without that information it is not possible to answer the question.
20' x 10' (200 square feet) = 22.22 square yards.
