Question

Find the perimeter of the triangle below. Round to the nearest hundredth.

Answer 1

63.63 in

Explanation:

Pythagorean Theorem:

a² + b² = c²

Applying Pythagorean Theorem:

a = 22, b = 15, c = ?

22² + 15² = c²

c² = 484 + 225

c² = 709

c = √709

Perimeter = 22 + 15 + √709 = 63.63 in (nearest hundredth)
