Answer 2

Answer:

Step 1. Find the base of the right angle triangle by Pythagoras theorem:-

$h^{2} = p^{2} +b^{2} \\(52)^{2} = (48)^{2} +b^{2} \\2704= 2304 +b^{2} \\b^{2} = 2704-2304\\b^{2} = 400\\b=\sqrt{400} \\b=20$

Step 2. Perimeter of ΔABC = AB + BC + AC

= AB + BC + AC

= 20 + 52 + 48

= 120

Perimeter of ΔABC is 120.
