Surface area covered by rectangular playground is 320 yards. The width of the playground is 20 yards using factors determine the length of the playground.

To determine the length of the playground, we can divide the surface area by the width:

Length = Surface area / Width
Length = 320 yards / 20 yards
Length = 16 yards

Therefore, the length of the playground is 16 yards.

To determine the length of the rectangular playground, we can use the formula for the surface area of a rectangle which is given by:

Surface Area = Length × Width

We are given that the width of the playground is 20 yards and the surface area is 320 yards. Plugging in these values into the formula, we get:

320 = Length × 20

To find the length, we can divide both sides of the equation by 20:

Length = 320 / 20

Simplifying the division, we get:

Length = 16

Therefore, the length of the playground is 16 yards.
