A landscaper is set to create a flower bed. Firstly, he measures the dimensions of the garden. Using this, he will be able to create a concrete path that is going to surround the grass area. The dimensions of the flower bed are shown in the diagram below, where x represents the width of the concrete path to be created.
the measurements are:
2.5m as height
4 m as width
The landscaper has a total area of 12m 2 of grass and concrete to work with. What would be
the area of the concrete needed to surround the flower bed? Use an algebraic equation to
prove your working.

w represents the width of the path
12 = (2.5 + 2w)(4 + 2w)
12 = 10 + 13w + 4w2
0 = 4w2 + 13w - 2
Cab you solve for w and answer?

There is some information about the dimensions or relative area of the grass missing. It is feasible to determine the total width of grass and concrete with this information, but not only the concrete.05/17/19
