Answer:
A = 62.35 cm2
Step-by-step explanation:
The perimeter of the equilateral triangle is 36cm
each side = 36/3 = 12 cm
The formula for area of an equilateral triangle is:
[tex]\frac{\sqrt{3} }{4}[/tex] (side)2
the side =12cm
area = [tex]\frac{\sqrt{3} }{4}[/tex] (side)2
=0.433 x (12)2
=0.433 x 144
area= 62.35 cm2
