Question

calculate the area and the height of an equilateral triangle whose perimeter is 60 CM​

Answer 1

Answer:

Step-by-step explanation:

Perimeter = 60

60 = a+a+a

60 = 3a

>>>> a = 20

Now,

Area of ∆ = √3×a^2/4

So, √3×20^2/4

Answer 2

Step-by-step explanation:

a+a+a=3a

60=3a

a=60/3

a=20

area=√3a^2/4

=√3*20*20/4

=√3*400/4

=√3*100

=100√3
