90 cm²
Step-by-step explanation:
Find the length of one side of the triangle:
Given that it is an equilateral triangle, all sides have the equal length.
Length of the side = Perimeter ÷ 3
Length of the side = 36 ÷ 3
Length of the side = 12 cm
Find the area:
Area = 1/2 x base x height
Area = 1/2 x 12 x 15
Area = 90 cm²
