Answer:

12 in and 36 in

Explanation:

(A)

Using Pythagoras' identity in the right triangle

b² + 9² = 15²

b² + 81 = 225 ( subtract 81 from both sides )

b² = 144 ( take the square root of both sides )

b =
√(144) = 12 in

(B)

The perimeter is the sum of the 3 sides, thus

perimeter = 15 + 9 + 12 = 36 in
