Answer 1

We are asked to find the perimeter of the given figure.

Recall that the perimeter is basically the sum of all the sides in the figure.

But the length of one side is missing that can easily be found.

Let me draw the figure to illustrate the idea.

Step 1: Find the length of the missing side

As you can see in the above figure,

We found the length of the missing side by subtracting the length of 9 ft from the 14 ft, which will give us the length of the missing side drawn in red color.

Step 2: Find the parameter of the figure

Now we can proceed to find the perimeter of the figure.

Add up the lengths of each side

`\begin{gathered} Perimeter=5ft+15ft+14ft+7ft+9ft+8ft \\ Perimeter=58ft \end{gathered}`

Therefore,

The length of the missing side is 5 ft

The perimeter of the figure is 58 ft

Note:

The unit of the perimeter of the rectangle is ft

Whereas the unit of the area of the rectangle is ft^2
