Question

Victoria wants to plant a vegetable garden in the shape of a square. she has a space allocated in her backyard that will accommodate 175 square feet. using the drawing below, use the foil method to find the polynomial that represents the area of the square. if x=6, will she have enough room to plant the garden?

Answer 1

The side is (2x+3)?  then the area is: (2x+3)(2x+3) = 4 x^2 + 12 x + 9  if x = 6 then Area = 4(36)+12(6)+9 = 144 + 72 + 9 = 225, too big :(
