Question 1084658
the area of the remodeled square deck is x^2 + 4x


the measure of each side of the original side of the square deck is x.


the area would be length * width.


with a square deck, the length and width are the same, therefore the area would be x * x = x^2.


he remodels by increasing the length of the deck by 4 feet.


therefore, the length is now (x + 4) and the width is still x.


the area of the remodeled deck is (x + 4) * x which is equal to x^2 + 4x.


everything checks out, but i'm not sure what the question is.


what solution are you looking for?
