Explanation:
To find side b use Pythagoras theorem:
Hypotenuse²=Base²+Height ²
17²=B²+15²
289-225=B²
64=B²
√8=B²
So,
8 yards is Side B
Now,
We can use Heron's Formula
√S(S-A) (S-B) (S-C)
Let's find semi perimeter
17+15+8/2
40/2=20
So, S=20
Let A=8,B=15,C=17
√20(20-8) (20-15) (20-17)
√20×12×5×3
√2×2×5×5×2×2×3×3 (Factorising the numbers)
2×5×2×2×3
120 yards Answer
