Chapter 0.7, Problem 7E

To determine

To calculate: The perimeter of the triangle with sides 4 feet, 13 feet and 12 feet.

Answer to Problem 7E

The perimeter of the triangle with sides 4 feet, 13 feet and 12 feetis $29\text{ feet}$ .

Explanation of Solution

Given information:

The triangle with sides 4 feet, 13 feet and 12 feet.

Formula used:

Perimeter $\left(P\right)$ of a polygon is sum of lengths of its sides.

Calculation:

Consider the triangle with sides 4 feet, 13 feet and 12 feet.

A triangle with different side length is provided. Lengths are 4 feet, 13 feet and 12 feet.

Recall that aperimeter $\left(P\right)$ of a polygon is sum of lengths of its sides.

Apply it,

  $\begin{array}{c}P=4+12+13\\ =29\end{array}$

Thus, the perimeter of the triangle with sides 4 feet, 13 feet and 12 feetis $29\text{ feet}$ .
