The width of a rectangle is two-thirds of its length, and its area is 216 square meters. what is the length? is it 27 or 12

The length of rectangle =18 m.

Step-by-step explanation:

Suppose of length of rectangle=x

Width of rectangle =

Area of rectangle =

We have to find the length of rectangle .

Area of rectangle =

Substitute the values in the given formula

By multiplication property of equality

( by division property of equality )

Substitute the value then we get

Width of rectangle =

Hence, the length of rectangle =18 m.
