Question 957336: a rectangle has a perimeter 600m. If the rectangle is x meter wide, express the area of the rectangle in terms of x Answer by macston(5194) (Show Source):
You can put this solution on YOUR website! Area=A; x=width; L=length; P=perimeter
P=2(L+x)
600m=2(L+x) Divide each side by 2.
300m=L+x Subtract x from each side.
300m-x=L
A=Lx Substitute for L
A=(300m-x)(x) ANSWER:A IN TERMS OF x.
