The length and width of the playground is 30 meter and 32/3 meter respectively.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.

Let x represent the width and y represent the length. Hence:

y = 3x - 2   (1)

Area = xy = 320

x(3x - 2) = 320

3x² - 2x - 320 = 0

x = 32/3 m

y = 3(32/3) - 2 = 30 m

The length and width of the playground is 30 meter and 32/3 meter respectively.
