Me ! 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

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

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
