The side of an equilateral triangle measures2√3 cm. Find its area.
Answer : 3√3 cm^2
Step by step explanation :
We know that,
Area of an equilateral triangle = (√3/4) × (side)^2
Side = 2√3 cm ( Given )
Area = (√3/4) × (2√3)^2
= (√3/4) × 2√3 × 2√3
= (√3/4) × 4 × 3
= (√3/4) × 12
= (√3) × 3
= 3√3
Hence,
Area of the equilateral triangle is 3√3 cm^2
