Question

If the area of an equilateral triangle is 196/3 cm?, then each of its sides is


​

Answer 1

GIVEN :

Area of an equilateral triangle = 196/3 cm^2

TO FIND :

Length of each sides

SOLUTION :

WE KNOW, area of an equilateral triangle formula is  $\frac{\sqrt{3} }{4} * (side)^2$

              or, $\frac{196}{3}$ = $\frac{\sqrt{3} }{4}$ * $side^{2}$

              or, side = 12.28 cm

Therefore, the length of the sides of equilateral triangle is 12.28 cm.
