## anonymous 4 years ago Workers plan to apply a reflective coating of paint to one surface of an equilateral triangular shaped highway sign. How many square inches of coating need to be applied to the sign if one side of the triangle is 14 inches?

1. anonymous

$(a ^{2}+b ^{2}+c ^{2})/4\sqrt{3}$ gives u area

2. anonymous

im only giving 14, what would b and c be

3. anonymous

all of the sides are equal

4. anonymous

equilateral triangle = all sides are the same length

5. Xishem

$A=\frac{\sqrt3}{4}s^2$Is what the formula should be.

that works thanks
