Answer:
The remaining area in the form of a polynomial function where 0 < x < 3.
Step-by-step explanation:
Breadth of rectangular piece of cardboard = 7 inches
Length of rectangular piece of cardboard = 20 inches
Area of cardboard =
Area of cardboard =
Area of cardboard =
Squares of length x inches on a side cut from each corner.
Length of square = x
Area of 1 square =
Area of 4 squares =
Area of remaining portion
So, the remaining area in the form of a polynomial function where 0 < x < 3.
