The answer depends on the units of measurement used for the numbers in the question: feet, metres, yards or something else.
20 = 5 x 4
25
If it is 8 feet by 5 feet then there are 8*5 = 40 square feet
20*5 = 100 square feet.
14 × 5 = 70 square feet.
25 square feet
8 * 5 = 40 square feet
5 feet 5 inches is 5.41667 feet. (5/12 = 0.41667)So, the area of the room is 6 x 5.41667 = 32.5 square feet
To find the measurements of a room with 15 square feet, you would need to consider the dimensions of the room. For example, a room that is 3 feet by 5 feet would have an area of 15 square feet (3 feet x 5 feet = 15 square feet).
75 square feet.
5' x 6' = 30 square feet.
Well, darling, a room that is 90 square feet could be about 9 feet by 10 feet, or any combination that multiplies to 90. It's not rocket science, honey. Just grab a tape measure and do the math, or ask someone else to do it for you.
