Question

HELP ME PLEASE!!! Heron's formula: Area=sqrt(s(s-a)(s-b)(s-c)) What is the area of triangle ABC? Round to the nearest square unit. ________ square units

Answer 1

s is a half perimeter of a triangle.

For given triangle,

s = (16+8+10) /2 = 17,

and a= 16, b=8, c=10.

Now, we can use Heron´s formula,

A=√(s(s-a)(s-b)(s-c)) = √(17(17-16)(17-8)(17-10)) = √(17*1*9*7) = √(1071) ≈ 33

A = 33 square units
