Question

if the perimeter of an equilateral triangle is 111 m, find the length of each side.​

Answer 1

Answer:

Let the all sides be x

so, perimeter = sum of all sides

111m=x+x+x

111m=3x

111/3=x

x=37 m

so all each side are 37m

Answer 2

Answer:

Perimeter = 111m

We know that p = sum of all sides.

Also, side of an equilateral triangles are equal.

Therefore,

a + a + a = 111

I.e. 3a = 111

So, a = 37

Hence each side measures 37 m
