The length of each side of an equilateral triangle is 22 cm. Find the area (in cm²) of this triangle.

Show answer & explanation

Correct answer: C

Explanation

The correct answer is Option 3 i.e. $121\sqrt3$ .

Given that

The length of each side of an equilateral triangle is 22 cm

Formula used

Area of an equilateral triangle = $\sqrt3$ /4 × (side)²

Calculation

Area = $\sqrt3$ /4 × (22)² = $\sqrt3$ /4 × 484 = $121\sqrt3$ cm²
