The width of a pavement around a building is uniform. The pavement is equal to 8500m$^2$ and the building is 120m by 80m. What is the width between the building and pavement?
I mapped it out and I can't seem to get it. I'm in grade 11 math.
Thanks!

The pavement width is $w$. The rectangle formed by the pavement (including building) has an area $A=(120+2w)\cdot(80+2w)$. You also know $A-120\cdot80=8500$. Can you take it from here?
