Answer: 1 Mark
In an equilateral triangle, all the sides are equal.
Let the side of an equilateral triangle be= a cm where a= 3.4 m ( given)
Now Perimeter = a+ a+a=(3a) m
= (3)*(3.4)
=10.2m
Hence perimeter of the equilateral triangle = 10.2m.
Now, 1 m= 100cm
∴ 10.2m=10.2×100 = 1020 cm.
Hence, the perimeter of the triangle is 1020 cm.
