The perimeter is the distance around rectangle. So, the perimeter of the

rectangle is the sum of the lengths of all four sides.

The perimeter P of a rectangle is given by the formula,

Where L is the length and is W is the width of the rectangle.

The perimeter P of a rectangle is

                        (Substitute L = 1.6 m and W = 0.9 m)

                                 (Add: 1.6 + 0.9 = 2.5)

                                         (Multiply: 2 X 2.5 = 5)

The perimeter of the rectangle is 5 m.
