Mrs. D. draws a large right triangle for her students, and shows that the two legs are 3 and 4 feet long, and the hypotenuse is 5 feet long. She computes that the area is 6 square feet. As an aside, she remarks that using inches, the side lengths would be 36, 48, and 60 inches. Jimmie wonders whether the area of the triangle would be 72 square inches since 12 6 = 72 (but he's afraid to ask). Is he correct? Explain
