Answer:

B. 7 and 60

C. 11 and 56

Explanation:

see the attached figure to better understand the problem

we know that

The area of the three squares must satisfy the Pythagorean Theorem

so


c^2=a^2+b^2

where

c^2 is the area of the largest square

a^2 and b^2 are the areas of the smaller squares


67=a^2+b^2

The sum of the areas of the smaller squares must be equal to 67

therefore

7 and 60 ----> could be the areas of the smaller squares (60+7=67)

11 and 56 ----> could be the areas of the smaller squares (11+56=67)

The diagram shows a right triangle and three squares. The area of the largest square-example-1
