Question

Identify the perimeter and area of an equilateral triangle with height 9 cm. Give your answer in simplest radical form. PLEASE HELP!!

Answer 1

The side length of the equilateral triangle would be 6√3. Therefore, the perimeter would be 18√3 and the area would be 27√3.

Area is derived from side length multiplied by height, which is 9, then dividing by 2.
