A triangle has side lengths of (6.2v-5.5)(6.2v−5.5) centimeters, (8.5v-6.7)(8.5v−6.7) centimeters, and (6.6w+7.6)(6.6w+7.6) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?

Given:

Side lengths of triangle are (6.2v-5.5) cm, (8.5v-6.7) cm, and (6.6w+7.6) cm.

To find:

The expression which represents the perimeter of the given triangle.

Solution:

We know that perimeter of a triangle is the sum of all sides of a triangle. So,

On combining like terms, we get

Therefore, the perimeter of the triangle is .

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
