Answer:
6 meters.
Step-by-step explanation:
Let w represent width of the rectangle.
We have been given that the area of a rectangle playground is 78 square meters. The length of the playground is 13 meters.
We know that area of a rectangle is width times length of rectangle. We can represent our given information in an equation as:
[tex]\text{Area of rectangle}=\text{Length}\times \text{Width}[/tex]
[tex]\text{78 m}^2=13\text{ m}\times \text{Width}[/tex]
[tex]\frac{\text{78 m}^2}{13\text{ m}}=\frac{13\text{ m}\times \text{Width}}{13\text{ m}}[/tex]
[tex]6\text{ m}=\text{Width}[/tex]
Therefore, the width of the rectangle is 6 meters.
