A small city park consists of a rectangular laawn surrounded on all sides by a 330 m2 border of flowrs 2.5m wide. Find the area of the lawn if the entire park is 5 m longer than it is wide.
x(x +5) -(x -10)(x - 15) = x +330
xsquared + 5x - x squared + 15x + 10x + 150 + x + 330
5x + 15x + 10x + 150 = x+ 30
30X + 150 = x + 330 - 150
30x = x + 280
after this I have absolutely no idea what to do.
Please show work and explain. Thanks
