The answer depends on the units used for 30 and 60. It should be obvious to you that the square footage of a 30 ft x 60 ft area will be somewhat different form that of 30 yards x 60 yards!
360 square feet !
30 square yards.
360 square feet. Multiply length by width - the result is the area in square feet.

15 x 2 = 30 square feet.
570 square feet.
30 square meters = ~322.92 square feet.
30 feet x 30 feet = 900 square feet.
24 x 30 = 720 square feet.
30 x 40 = 1200 square feet.
30 acres = 1,306,800 square feet.
20' x 30' = 600 square feet.
30 inches by 5 feet = 12.5 square feet.
30 inches by 10 feet = 25 square feet.
30 feet x 30 feet = 900 square feet 900 square feet = 83.612736 square metres.
30 x 70 = 2,100 square feet.
30 x 60 = 1800 square feet
