Mr. Chambliss is planning to build a shed with a rectangular floor. In his original plan, the length of the floor was 7 feet and

the area of the floor was 35 square feet. In his new plan, he wants to extend the length by 3 more feet. If the total area of the shed will be 70 square feet, by how many feet will he have to extend the width?

Basically he is doubling his original area...

Since A=LW the original W=35/7=5...

70=(7+3)(5+x)

70=10(5+x)

7=5+x

x=2

So he will have to extend the original width by 2 ft
