Chapter 10: Q.2 (page 538)

The perimeter of an equilateral triangle is 42 meters. Find the length of each side.

Short Answer

Expert verified

The length of each side of the triangle is 14 meters each.

Step by step solution

01

Step 1. Given Information.

The perimeter of the triangle is 42 meters.

02

Step 2. Calculation.

The perimeter of the triangle is 42 meters and since all the three sides of the triangle are equal, Let the length of the side be as x.

x+x+x=42

Add all x together.

3x=42

Now, divide both sides by 3.

3x3=423

This will give,

role="math" x=14

03

Step 3. Conclusion.

Since, it is an equilateral triangle, all the three sides of the triangle are same hence, the length of each side is 14 meters.
