Mike would like to enlarge his rectangular front yard which is currently 80 feet by 40 feet. He can only extend the width and length by 5x feet. If x = 7 feet, what will be the increase in area of the front yard?
How can this problem be raised to a higher level of complexity
I am wonder what width and length means..is that the sum, or each?
I will assume it is each width and length.
but this is an INCREASE of
600x+25x^2 or you do it for x=7
