- 4 = (-6 – (-2)) / (r – 8)

- 4 = - 4 / (r – 8)

r – 8 = 1

r = 9

how do I find the area of an equilateral triangle given the perimeter of 60 and the height of 17.3 cm?

guajiro [1.7K]

If perimeter is 60 so the side is 60 ÷ 3 = 20

Now we can apply the area formula for triangles;

$A=\frac{1}{2}.b.h\\
\\
A=\frac{1}{2}.20.17.3=10.17.3=173 \ cm^2$
