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
