WebStep 1: Find the side of an equilateral triangle using perimeter. 3a = 12 a = 4 Thus, the length of side is 4 cm. Step 2: Find the area of an equilateral triangle using formula. Area, A = √3 a 2 / 4 sq units = √3 (4) 2 / 4 cm 2 = 4√3 cm 2 Therefore, the area of the given equilateral triangle is 4√3 cm 2 WebThe formula is: Area = w × h w = width h = height We know w = 5 and h = 3, so: Area = 5 × 3 = 15 Example: What is the area of this circle? Radius = r = 3 Example: What is the area of this triangle? Height = h = 12 Base = b = 20 Area = ½ × b × h = ½ × 20 × 12 = 120 A harder example: Example: Sam cuts grass at $0.10 per square meter
