jamierox4ev3r · Answer

soo.. you would first create an equation to represent the perimeter of the base of the building

jamierox4ev3r · Answer

so that would be p=2l +2w. We don't have all the numbers though, so we alter the equation a bit based on the data that we have above

jamierox4ev3r · Answer

So our P=Perimeter, and L=2w-75, while w is just w

jamierox4ev3r · Answer

fill the equation based from this, then solve for w. once you have w (of the width), just solve for length by plugging in the width answer! :)

what formula do you use first ?
