Question

Find the area of triangle with sides 12,9.6&7.2

Answer 1

Side a = 12 , Side b = 9.6, Side c = 7.2

Formula for area of triangle:

Area of triangle = √p(p-a)(p-b)(p-c)

Find semi-perimeter:

p = 1/2 (12 + 9.6 + 7.2) = 14.4

Find the area:

area = √14.4(14.4 - 12)(14.4 - 9.6)(14.4 - 7.2)

area = 34.56 units²

Answer: The area is 34.56 units²
