Question

What is the area of an equilateral triangle with side 2 cm?
a) √6 cm^2
b) √3 cm^2
c) √8 cm ^2
d) 4 cm square​

Answer 1

Step-by-step explanation:

a = 2 cm

√3 = 1.73

Area of an equilateral triangle= √3/4 ×a²

                                              = √3/4 × 2²

                                              = √3/4 × 4

                                              = √3

                                              = 1.73 cm ²

Answer 2

Answer:

Step-by-step explanation:

Given that

The side of the equilateral triangle

=2 cm

So area of the triangle=√3/4(side)²

=√3/4×2²=√3/4×(4)=√3 sq. cm

So option B is the correct answer.

Hope you got it.
