Question

Determine the perimeter of the right triangle shown.

Answer 1

The answer is 30
Explanation: 5+12+13=30

Answer 2

30

Explanation:

length of horizontal leg = 12 (7 - -5 = 12)

length of vertical leg = 5 (3 - -2) = 5)

length of hypotenuse = √12² + 5² = √169 = 13

Perimeter = 12 + 5 + 13 = 30
