Question

Leanna has a rectangular piece of fabric. The fabric is 24 inches wide and 40 inches long. Leanna folds the piece of fabric along its diagonal to form a triangular scarf.

What is the area, in square inches, of the triangular scarf?

Answer 1

480 square inches

width = base = 24 inches

length = height = 40 inches

area of the triangular scarf = 1/2 * base * height

= 1/2 * 24 * 40

= 480 square inches
