Question:

What is the perimeter, in inches, of a rectangular wall that measures 6 feet 4 inches by 8 feet 3 inches?

A 350
explanation

To begin, find the length of each side in inches. 6 feet 4 inches is equal to 72 inches + 4 inches = 76 inches. 8 feet 3 inches is the same as 96 inches + 3 inches = 99 inches. The perimeter is (76 × 2) + (99 × 2) = 152 + 198 = 350 inches.
