Problem |
Find the area of the equilateral triangle ABC, where AB = AC = BC = 8cm. |
|
2 |
Step |
Given that |
AB = 8 cm , BC = 8 cm ,CA = 8 cm |
3 |
Step |
To find the area of an equilateral triangle, you can use the formula: A = \$(\sqrt3)/4 \times a^2\$ ( hint a = sides ) |
|
4 |
Step |
Substitute the values into the formula: |
A = \$(\sqrt3)/4 \times 8^2)\$ |
5 |
Step |
Calculate the area |
A = \$(\sqrt3)/4 \times 64 cm^2\$ A = \$((\sqrt3) \times 64)/4 cm^2\$ |
6 |
Step |
After Simplify the equation: |
A = \$(\sqrt3) \times 16 cm^2\$ A = \$16(\sqrt3) cm^2\$ |
7 |
Solution |
Therefore, the area of the equilateral triangle ABC is \$16(\sqrt3) cm^2\$. |

Choice-A |
This option is Incorrect, as the correct area is \$16(\sqrt3)(cm)^2\$ |
Wrong \$14\sqrt(3) cm^2\$ |
10 |
Choice-B |
This option accurately calculates the area of an equilateral triangle with a side length of 8 cm and confirms its precision. |
Correct \$16\sqrt(3) cm^2\$ |
11 |
Choice-C |
This option is Incorrect, as the correct is 16 \$16(\sqrt3)(cm)^2\$ |
Wrong \$13 \sqrt(3) cm^2\$ |
12 |
Choice-D |
This option is Incorrect. The area should have units of square centimeters \$cm^2\$, not centimeters cm |
Wrong \$15\sqrt(3) cm^2\$ |
