# The area of a rectangular field is $720\ m^2$, if its width is $18\ m$ what is its length?

Given:

The area of a rectangular field is $720\ m^2$ and its width is $18\ m$.

To do:

We have to find the length of the rectangle.

Solution:

We know that,

Area of a rectangle of length $l$ and breadth $b$ is $lb$.

Let the length of the rectangle be $x$.

This implies,

$720=18\times x$

$x=\frac{720}{18}$

$x=40\ m$

**Therefore, the length of the rectangle is $40\ m$.**
