The area of a rectangle is 48 square feet. the length is 8 feet longer than the width. 1) which picture corresponds to the problem? 2) what are the dimensions of the rectangle?

1) The picture whose width = x and Length = (x + 8) feet

2) Width = 4 feet

   Length = 12 feet

Step-by-step explanation:

A rectangle has one side longer than the other.

Area of a rectangle = product of its sides.

                                  = length × width

Width = x feet

Length = (x + 8) feet

Area = 48

∴ x × (x + 8) = 48

   x² + 8x = 48

  x² + 8x + 4² = 48 + 4²

  (x + 4)² = 64

 x + 4 = √64

x = ±8 - 4

x = - 12        or x = 4

     Since length can not be negative, x = 4

∴ Width = 4 feet

   Length =4 + 8 = 12 feet
