Answer

Problem

The perimeter of an equilateral triangle is equal to 270 cm. What is the length of one side of this triangle?

Formula used

\$"Perimeter" = "side" + "side" + "hypotenuse"\$

Step - 1

Given that,

The perimeter of an equilateral triangle = 270 cm

Step - 2

Let x be the length of one side of an equilateral triangle, then its perimeter is equal to 3x

Step - 3

Then, \$\cancel3^1x = \cancel(270)^90\$

\$x = 90\$

Step - 4

Hence,the length of one side of this triangle is 90 cm.
