Answer:
2nd leg^2 = 17^2 + 15^2
2nd leg^2 = 64
2nd leg = 8
a = 17 b = 15 c = 8
We use heron's formula to find area when we know 3 sides.
We first must calculate the semi-perimeter:
semi-perimeter = 17 + 15 + 8 / 2 = 20
area = square root [s * (s -a) * ( s-b) * (s-c)]
area = sq root [20 * 3 * 5 * 12]
area = sq root [3,600]
area = 60 square meters
