Question 1063412: a rectangular building whose depth is twice its frontage is divided into two parts by a portion that is 20 ft from and parallel to the front wall.If the rear portion of the building contains 3500 ft^2 find the dimwnsions of the building.

You can put this solution on YOUR website!
x= frontage of the building, in feet.
So, the area of the rear portion of the building, in square feet
is represented by
20x ,
and our equation is
20x=3500 .
Solving that equation gives us x=175 .
so the building's frontage is highlight%28175feet%29 ,
and so since it's depths is twice its frontage,
the building's depth is 2%2A%28175feet%29=highlight%28350feet%29 .
