Answer 1

Step-by-step explanation:

I think its normal we know that side of equalateral tringle equal each other, that why answer will be 180

Answer 2

Rohan’s answer is incorrect

Perimeter of equilateral triangle is 3a=60

So side (a) = 20

Area of equilateral triangle is given by root(3)/4 * a^2

So area in this case is

Root(3)/4 * 20^2

= Root3 / 4 * 400

= Root3 * 100

= 100 root3 = 173.2 (app)
