Question

Find the area of an equilatera triangle whose side is 4cm

Answer 1

Area of an equilateral triangle is given by $\dfrac{\sqrt{3}}{4} a^2$ unit sq

where a is the length of the sides of the triangle.

In this case, the area is
$\dfrac{\sqrt{3}}{4} \times 4^2$
$= \sqrt{3} \times 4$
$=4\sqrt3$ cm^2

That is your answer.

Answer 2

Area of equilateral triangle whose side is 4 cm is :- 6.93 cm sq.
