A glass company is repairing a window in the shape of an equilateral triangle. If the length of one side of the triangle is 17 inches and the company charges $12 per square inch, the cost of the replacement window will be $___.

Answer 1

the cost of the replacement window will be $1501.44.

Explanation:

area of an equilateral triangle:

`A = (√(3))/(4) a^(2)`

A = (√3)/4 * (17)^2

A = 125.12 in^2

125.12 * 12 = $1501.44
