504 square feet.
13 ft x 42 ft = 546 sq ft
More information is required. In what units is 58? Inches, feet, yards, miles, metres? Likewise, what are the units for 54?
It is not possible to answer the question because you have filed to specify the units used for the dimensions of the room. It should be blindingly obvious to anybody that the square footage of a 9 ft x 6 ft room will be quite different from one which is 9 yards x 6 yards.
The square footage of a radius is meaningless, but if you mean the square footage of a circle of radius say R, the answer is 3.142 x R x R
33 x 42 = 1,386 square feet.

42 inches = 3.5 feet48 inches = 4 feetThe area of a rectangle that measures (42" by 48") is (3.5 x 4) = 14 square feet.

The square footage of a radius is meaningless, but if you mean the square footage of a circle of radius say R, the answer is 3.142 x R x R
The answer depends on the units used for 6 and 9. It should be obvious to you that the square footage of a 6 ft x 9 ft area will be somewhat different form that of 6 mile x 9 miles!
Length x width = square footage
The square footage, or area, of a 14' x 23' rectangle would be 322' squared.
