Question

15. The new county park is one mile square. What would be the length of a road around its boundaries?

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

County park:

area = 1 mile²

Step 02:

length of a road around:

area = side²

1 mile ² = s²

`\begin{gathered} s^2=1 \\ s=\sqrt[]{1}=\text{ 1 } \end{gathered}`

s = 1 mile

perimeter = 4 s = 4 * 1 mile = 4 miles

The answer is:

the length of a road around its boundaries is 4 miles
