perimeter of equilateral∆ = 3a where a = side
3a = 72
a = 72/3
a = 24
finding the area of ∆ by Heron's formula...
S = 72/2
= 36
hence area =>> 144√3
3a = 72
a = 72/3

HEYA MATE!
YOUR ANSWER....
Perimeter of equilateral triangle = 3× length of one side.
Given perimeter is 72 cm.
According to the formula,
72=3x
x=24cm.
So, length of one side is 24 cm.
Now, area of equilateral triangle =
Substituting the values, we get
If you're facing any kind of problem in solving in this way, then you can use Heron's formula.
