Q. alculator Allowed\newlineAlgebra I, Subpart 33\newlineThe length of a garden is 66 feet more than the width. The area of the garden is 4040 square feet.\newlineWhat is the length, in feet, of the garden?\newlineEnter your answer in the space provided.
  1. Define Variables: Let's call the width of the garden ww (in feet). Then the length is w+6w + 6 feet.
  2. Calculate Area: The area of a rectangle is given by the formula length×width\text{length} \times \text{width}. So, the area of the garden is (w+6)×w(w + 6) \times w.
  3. Set Up Equation: We know the area is 4040 square feet, so we set up the equation (w+6)×w=40(w + 6) \times w = 40.
  4. Expand and Simplify: Now we need to solve for ww. Expanding the equation gives us w2+6w=40w^2 + 6w = 40.
  5. Factor the Equation: To solve the quadratic equation, we need to set it to zero. So, w2+6w40=0w^2 + 6w - 40 = 0.
  6. Set Factors to Zero: We can factor this equation to find the values of ww. Factoring gives us (w+10)(w4)=0(w + 10)(w - 4) = 0.
  7. Solve for Width: Setting each factor equal to zero gives us w+10=0w + 10 = 0 or w4=0w - 4 = 0.
  8. Find Length: Solving for ww, we get w=10w = -10 or w=4w = 4. Since width can't be negative, we take w=4w = 4 feet.
  9. Find Length: Solving for ww, we get w=10w = -10 or w=4w = 4. Since width can't be negative, we take w=4w = 4 feet.Now we find the length by adding 66 to the width. So, the length is 4+6=104 + 6 = 10 feet.
