The width of a small playground 3 meters less than the length of the playground. if the area of the playground 54 square meters. what are the dimensions of the playground.

Length = 9 meters

Width = 6 meters

Step-by-step explanation:

The diagram of the playground is shown in the attached photo

The width of a small playground 3 meters less than the length of the playground.

Length of playground = L meters

Width of playground = (L-3) meters

The area of the playground is 54 square meters.

Area = L × W

54 = L(L - 3)

54 = L^2 - 3L

L^2 - 3L - 54 = 0

L^2 + 6L - 9L- 54 = 0

L(L+6) - 9(L+6) = 0

(L-9)(L+6) = 0

L -9 = 0. or L+6 = 0

L = 9 or L = -6

L cannot be negative so, the length of the playground is 9 meters

The width of the playground is

L-3 = 9-3 = 6 meters
