Chapter 10: Q.17 (page 540)

Find the unknown side length of the triangle given the perimeter P. Then classify the triangle by its side lengths.
$P = 84.3 cm$

Short Answer

Expert verified

The length of all the three sides is $28.1 cm$ each and the triangle is an equilateral triangle.

Step by step solution

Step 1. Given Information.

Perimeter of the triangle is $84.3 cm$ .

Length of all the three sides is same.

Step 2. Calculation.

Perimeter of the triangle is $84.3 cm$ .

Let the length of one side of triangle be x.

Since all the three sides of the triangle are same -

$x + x + x = 84.3$

Now add all x together.

$3 x = 84.3$

Now, divide both sides by 3.

$\frac{3 x}{3} = \frac{84.3}{3}$

This gives us,

$x = 28.1$

Since, all the three sides are same, the length of each side is $28.1 cm$ .

Step 3. Conclusion.

The length of all the three side is $28.1 cm$ each.

Since, all the three sides of the triangle are same it is an equilateral triangle.
