the length of a playground id 6 meters less than 3 times its width. If the perimeter of the playground is 100 meters what is the lenght and width of the area to the nearest hundredth meter?

Answer 1

grahaping
y=3

Answer 2

Length is 6 less than 3xwidth so L=3W-6
Perimeter = L+L+W_W or 2L+2W
Perimeter is 100m so 2L+2W=100

You have 2 equations and 2 unknowns so you can solve it.
