Problem

Find the area of the equilateral triangle ABC, where AB = AC = BC = 8cm.

Step

Given AB = 8Ccm , BC = 8cm , CA = 8cm

Formula:

Area of equilateral Triangle

\$(sqrt 3)/4 \times (a) ^ 2\$

Hint

Hint a = sides

Step

Substitute the values

\$((sqrt3) / 4 \times (8 cm) ^ 2 )\$

Step

\$(sqrt3) / 4 \times 64 (cm)^2\$
⇒ \$((sqrt3) \times64)/4 (cm)^2\$

Step

After simplification

\$(sqrt3) \times 16(cm)^2\$

Step

Therefore, the area of the equilateral triangle ABC

\$16(sqrt3)(cm)^2\$
