We'll recall the following formula that gives the area of
a triangle:
A = side*side*sine of the angle
included/2
Since the lengths of the sides of an equilateral
triangle are equal, let the length of the side be x.
A =
* sin 60/2
10.2 = *
/4
40.8 =
x
= m
x = 4.853
m
Therefore, the requested length of the side
of equilateral triangle is x = 4.853 m.
