Perimeter of equilateral triangle=3×side60=3side
60/3=side
20m=side
gence the side of equilateral triangle is 20metre
We know that each sides of an equilateral triangle are same in length.
Let the length of each of those three sides of the given equilateral triangle be a metre.
Therefore, a+a+a = 60
or, 3a = 60
or, a = 60÷3 = 20
Hence, each sides of this equilateral triangle measure 20 metre.
