Marsha used about 400 square 1-inch tiles to cover the tabletop that was shaped like a right triangle. The length of one leg of the right triangle was 16 inches. What was the length of the other leg of the triangle?

The area of the right triangular tabletop is calculated through the equation,

A = 0.5 (L₁) (L₂)

The area, as stated above, is equal to 400 in². Substituting the known values to the equation above,

400 = 0.5 (16 in) (L₂)

The value of L₂ is equal to 50 inches. Thus, the second length is equal to 50 inches.
