6. The original length, L, and original width, W. of a rectangular garden are BOTH increased by 3 feet each.
Write an expression to show
A. the AREA of the NEW rectangle
B. the PERIMETER of the NEW rectangle

Explanation:

A rectangle is a two-dimensional quadrilateral.

The area is given as:

      Area of a rectangle  = length x width

     Perimeter = 2(L+ W)

where L is the length and W is the width

Condition:

If L and W are increased by 3 feet each;

      New length  = L + 3

      New width  = W + 3

Area of new rectangle;

                   Area  = (L + 3) x (W + 3)

                             = LW + 3L + 3W + 9

Perimeter of new rectangle;

                    Perimeter = 2(L+3 + W + 3)

                                       = 2(L+W +6)
