Problem

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

Formula

The area of an equilateral triangle is

\$(\sqrt(3) / 4) × (side)^2\$

Step

In the equilateral triangle, ABC are equal and given each side is 8cm.

Step

After substituting the values, we obtain the resulting values.

\$(\sqrt(3) / 4) × (8 cm)^2\$

Step

After multiplication

\$(\sqrt(3) / 4) × 64 (cm)^2\$

Step

Now, we perform division.

\$(64 \sqrt(3)) / 4 (cm)^2\$

⇒ \$(16 \sqrt(3)) cm^2\$

Step

Then ,the area of the equilateral triangle is \$(16 \sqrt(3))cm^2\$

SumUp

Can you summarize what you’ve understood in the above steps?

Choice.A

The correct answer corresponds to the equilateral triangle’s area being equal to the selected option

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

Choice.B

The chosen option doesn’t correspond to the correct answer; the equilateral triangle’s area is misrepresented, making it incorrect

\$18(sqrt3)(cm)^2\$

Choice.C

The chosen option doesn’t correspond to the correct answer; the equilateral triangle’s area is misrepresented, making it incorrect

\$6(sqrt3)(cm)^2\$

Choice.D

The chosen option doesn’t correspond to the correct answer; the equilateral triangle’s area is misrepresented, making it incorrect

\$16(sqrt4)(cm)^2\$
