# The base of an inclined triangle is 6.5 cm, and the length of the lateral side is 0.8

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.
