thanks in advance guys. problem is below
Find the area of a triangle with sides measuring 4mm, 5mm, and 7mm.
Find the area of a triangle with sides measuring 4mm, 5mm, and 7mm.
-
s = (4 + 5 + 7) /2 = 8
Area of triangle = sqrt(s(s-a)(s-b)(s-c)) = sqrt(8*4*3*1) = sqrt(96) = 9.79
Area of triangle = sqrt(s(s-a)(s-b)(s-c)) = sqrt(8*4*3*1) = sqrt(96) = 9.79
-
apply Heron sqrt(p(p-a)(p-b)(p-c) where p is semi perimeter and a,b,c are the sides of the triangle
