    (Substitute l = 16 and w = 7)

          (Add: )

in           (Multiply: )

The find out Area:

Area of the rectangle is where l is the length and w is the width.

      (Substitute l = 16 and w = 7)

  (Product of two same signs is positive)

in         (Multiply: )

The perimeter (P) = 46 in and area (A) = 112 in.
