Chapter 0.7, Problem 2E

To determine

To calculate: The perimeter of the figure given.

Answer to Problem 2E

The perimeter of the figure is $38\text{km}$ .

Explanation of Solution

Given information:

The figure given in the question.

Formula used:

Perimeter $\left(P\right)$ of rectangle with length $\left(l\right)$ and breadth $\left(b\right)$ is denoted by $P=2\left(l+b\right)$ .

Calculation:

The figure is a rectangle as its opposite sides are equal and each angle is right angle. So, length is $8\text{km}$ and breadth is $11\text{km}$ .

Recall that aperimeter $\left(P\right)$ of rectangle with length $\left(l\right)$ and breadth $\left(b\right)$ is denoted by $P=2\left(l+b\right)$ .

Apply it,

  $\begin{array}{c}P=2\left(l+b\right)\\ =2\left(8+11\right)\\ =38\end{array}$

Thus, the perimeter of the figure is $38\text{km}$ .
