Respuesta :

"Square inches" means area, so 60" wide and 3 feet long is multiplied, however, they have to be in the same unit. So, 3 feet = 36 inches since 1 foot is 12 inches and 3(12) = 36. 

Therefore, 60 inches * 36 inches = 2,160 square inches of fabric.
3 ft*12= 36 inches

The area of a rectangular piece of fabric is equal to length times width.

36 in*60 in=2160 in^2

Final answer:2160 in^2
