The find out Perimeter:

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

    (Substitute l = 4.9 and w = 3.5)

              (Add: )

m             (Multiply: )

The find out Area:

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

      (Substitute l = 4.9 and w = 3.5)

  (Product of two same signs is positive)

        (Multiply: )

The perimeter (P) = 16.8 m and area (A) = .
