Question

I know the first part of doing this, but I forgot the other parts

Answer 1

17.

From the figure we can conclude:

`\begin{gathered} length=l=4-(-3)=7 \\ width=w=2-(-1)=3 \end{gathered}`

In order to calculate how much string will he need, we need to calculate the perimeter. The perimeter can be calculated as follows:

`\begin{gathered} P=2w+2l \\ so: \\ P=2(7)+2(3)=14+6=20 \end{gathered}`

Answer:

He will need 20 units
