a corner lot that was originally square lost 185m^2 area when one of the adjacent streets was widened by 3m and the other was widened by 5m. find the new dimensions of the lot.(hint:let x equal the length of a side of the original square lot)
It might help to draw a diagram. That's difficult to do here, so I'll set up the equation and see if you can figure it out from there.
3(x - 5) + 5x = 185
Solve for x. Once you have x, you can determine the new dimensions of the lot.
Remember that x will equal the length of one side of the original square lot.
