Question

Isabella owns a rectangular lot with an area of a square mile. If the length of the western side of her lot is a mile, what is the length of the northern side? How can you find the length?

Answer 1

The area of a rectangle is given by:

`A=w\cdot l`

Where "A" is the area, "w" is the width and "l" is the length.

In this problem the area of the lot is equal to "1 square mile" and the length is "1 mile". We can find the width with this information, we just need to use them in the formula above.

`\begin{gathered} 1=1\cdot w \\ 1=w \\ w=1 \end{gathered}`

The width is also 1 mile.
