Use the diagram below to answer the question that follows. Three squares are arranged as shown in the diagram above. The area of square X is 16 square inches, and the area of square Y is 9 square inches. What is the length of a side of square Z? A. 4 inches B. 5 inches C. 7 inches D. 9 inches

Solution

This is a typical pythogoras problem:

So, X^2 + Y^2 = Z^2

16 + 9 = 25 = Z^2

Z = 5

B. 5 inches
