| **The base of an inclined triangle is 6.5 cm, and the length of the lateral side is 0.8 times the length of the base. Calculate the perimeter of the triangle.**

Before solving the problem, you need to remember how to find one hundred percent.

To do this, you must first divide a known number by a known number of percent and then multiply by one hundred. This rule is required for this task.

Condition:

Given: An isosceles triangle with a base of 6.5 cm.

Side = 0.8 from the base.

Find the perimeter of the triangle.

Solution:

1) 6.5 / 80 * 100 = 8.125 – sides (by theorem).

2) 6.5 + 8.125 * 2 = 22.75 cm.

Answer: Perimeter of a triangle = 22.75 cm.
