Question

What is the length of each side of an equilateral triangle whose area is 4 root 3 cm square?

Answer 1

Area of equilateral triangle=a^2√3/4

4√3=√3/4a^2

16=a^2

a=4

Length of side is 4cm

Answer 2

Formual for area of equilater triangle is root 3/4 a^2

4 root 3 = root 3/4 a^2
a^2 = 4root 3*4/3
a^2 =16
a=root 16
a=4
