Question 62
The area of a table top in the shape of an equilateral triangle is $$9\sqrt{3}$$ cm$$^2$$. What is the length (in cm) of each side of the table?
Solution
Let the length of each side of the table = a
The area of a table top in the shape of an equilateral triangle is $$9\sqrt{3}$$ cm$$^2$$.
$$\frac{\sqrt{3}}{4}$$a$$^2$$ = $$9\sqrt{3}$$
a$$^2$$ = 36
a = 6 cm
Length of each side of the table = 6 cm
Hence, the correct answer is Option A
