Mr. Academia wants to enclose his rectangular parking lot by putting a wire fence on the three sides as shown in the figure. The total length of the wire is 80m. If we let w be the width and l be the length, what is the expression for the sum of the measures of the three sides of the parking lot?

• $w+l=80$

• $2w+l=80$

• $2l+w=80$

• $2w+80=l$

Mr. Academia wants to enclose his rectangular parking lot by putting a wire fence on the three sides as shown in the figure. The total length of the wire is 80m. Express the area (A) of the parking lot in terms of the width.

• $A=w\left(80-2w\right)$

• $A=w\left(80-w\right)$

• $A=w\left(2w-80\right)$

• $A=w\left(w-80\right)$
