Question

Find the area of an equilateral triangle whose side is 8 m. Give your answer correct to two decimal places.

Answer 1

Step-by-step explanation:

Given :

Side of an equilateral triangle is 8 m.

Find :

The area of an equilateral triangle.

Solution :

Area of an equilateral triangle

$\frac{ \sqrt{3} }{4} \times (side) ^{2}$

$\frac{1.73}{4} \times (8)^{2}$

$\frac{1.73}{4} \times 64$

$1.73 \times 16$

$27.68 \: \: m^{2}$

Hence :

Area of an equilateral triangle is 27.68 m².

Answer 2

Answer:

Area of an equilateral triangle

$\frac{ \sqrt{3} }{4} \times (side) ^{2} \\ \frac{1.73}{4} \times (8)^{2} \\ \frac{1.73}{4} \times 64 </p><p> \\ 1.73 \times 161.73×16 \\ 27.68 \: \: m^{2}27.68m$

Hence :

Area of an equilateral triangle is 27.68 m².
