Chapter 10: Q.16 (page 540)

Find the unknown side length of the triangle given the perimeter P. Then classify the triangle by its side lengths.
$P = 22.5 yd$

Short Answer

Expert verified

The length of the other two sides is $8.1 yd$ each.

The triangle is an isosceles triangle.

Step by step solution

Step 1. Given Information.

Perimeter of the triangle is $22.5 yd$ .

Length of one side is $6.3 yd$ .

Length of remaining two sides is same.

Step 2. Calculation.

Let the length of one side of triangle be x.

Since two sides of the triangle are same.

$x + x + 6.3 = 22.5$

Now add both x together.

$2 x + 6.3 = 22.5$

Subtract $6.3$ from both the sides.

$2 x + 6.3 - 6.3 = 22.5 - 6.3$

This gives us,

$2 x = 16.2$

Now, divide both sides by 2.

$\frac{2 x}{2} = \frac{16.2}{2}$

This gives us,

$x = 8.1$

Both the sides of the triangle are $8.1 yd$ each.

Step 3. Conclusion.

The length of the unknown side is $8.1 yd$ each.

Since, two sides of the triangle are same and one is different it is an isosceles triangle.
