Need to know: Heron's formula for computing Area of Triangle knowing the length of its sides a,b,c with s being 1/2 the Perimeter of the Triangle.
Area =
Question states the following to be true: Sides are 6, 8, 10
Perimeter of the triangle is 24
s = 12
substituting gives:
Area =
Area =
Area = 24
Rectangle B has an equal area with a width of 4
A = w*H
4*H = 24
H = 6
Perimeter of the Rectangle is 2*w + 2*h or in more detail:
4 + 4 + 6 + 6 = 20
