The Answer to this question is 5625√3 m²

Step-by-step explanation:

perimeter = 3 * a = 450 m

side a = 150 m

Altitude = AD     Base = BC.   AD ⊥ BC  .  D is the midpoint of BC.

Using Pythagoras th.:   AD² = AC² - DC² = a² - (a/2)²  = 3 a² / 4

Altitude of an equilateral triangle = √3/2 * a

Area = 1/2 * base * altitude

        = √3 a² / 4 = √3 * 150² / 4 = 5625√3 m²
