To calculate the area of a triangle from its three sides a, b and c is:
First find s = ½ (a + b + c), the area of the triangle = [s(s-a)(s-b)(s-c)]1/2
a, b ,c > 0 and s(s-a)(s-b)(s-c) > 0.
The answer is 42 .....thats just weird
Love your work occy and dont listen to them mate make it bigger. There just jealous they wont be able to catch you with 42 square meter sail.
