Q. 22 A

# The numerical values of area and height of an equilateral triangle are equal. What is the length of side of triangle?

Answer :

Since the numerical values of area and height of an equilateral triangle are equal

⇒ , where a is side of the triangle

Length of the side of the triangle a=

= 2 units
