First, to find the length of the second leg, we use the Pythagorean theorem.
51 squared – 45 squared = 2601 – 2025 = 576.
Here, a calculator will help us in calculations.
The root of 576 is 24.
Now all that remains is to add all the sides and find the perimeter of the triangle.
51 + 45 + 24 = 120 cm.
Answer: P = 120 cm.
