Answer :

To find the perimeter of a triangle, you need to add up the lengths of all its sides. The perimeter is the total distance around the triangle.

Given the side lengths of a triangle:

  1. One side measures 176 inches.

  2. Another side measures 274 inches.

  3. We don't have the exact measure of the third side, which is noted as '? in'.

To calculate the perimeter, we need the length of all three sides. Once we have that missing length, we can use the formula:

[tex]\text{Perimeter} = \text{Side 1} + \text{Side 2} + \text{Side 3}[/tex]

Substitute the known values:

[tex]\text{Perimeter} = 176 + 274 + (?\text{ inches})[/tex]

Once you find the missing measurement, simply plug it into the equation above to find the total perimeter. If you already have the information for the missing side, you can proceed to sum them up to get the perimeter. Otherwise, this missing measurement needs to be identified first to complete the calculation.
