What will be closest to the length, in feet, of the longest edge of his garden?
A. 2
B. 4.5
C. 7.2
D. 10

Answer 1

7.2

Explanation:

use the Pythagorean theorem to find the length of the hypotenuse

a squared+ b squared= c squared

4 squared+ 6 squared = c squared

16+ 36= c squared

52= c squared

52 = 7.2 squared
