Question

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

Answer 1

Given :-

• Side of Equilateral Triangle (a) = 8m

To Find:-

• Area of Equilateral Triangle

Solution :-

We know that,

• Area of Equilateral Triangle

$= > \frac{ \sqrt{3} {a}^{2} }{4} \\ = > \frac{ \sqrt{3} \times {8}^{2} }{4} \\ = > \frac{ \sqrt{3} \times 64 }{4} \\ = > \sqrt{3} \times 16 \\ = > 1.73 \times 16 \\ = > 27.68 {cm}^{2}$

Answer 2

Answer:

Area of equilateral Triangle = √3/4×a^2

= √3/4×8^2

= √3/4×64

= √3×16

= 1.73×16

= 27.68 cm^2
