Question

Find the area of an equilateral triangle whose each measures $8cm$.

• A. 16$c{m}^2$
• B. 16$\sqrt{3}c{m}^2$
• C. 15$\sqrt{3}c{m}^2$
• D. 14$\sqrt{3}c{m}^2$

Answer 1

The correct option is B 16$\sqrt{3}c{m}^2$

Given that side of an equilateral triangle is 8 cm.

Now we know that Area of an equilateral triangle= √3/4( side)²

So

Area= $\sqrt{3}$/4$\times 8\times 8$

= 16√3 cm²
