How will the perimeter of the rectangle change if its width is increased by 1m 30cm?

If one side of the rectangle is increased by 1 m 30 cm, then the second side will also increase by 1 m 30 cm, since in a rectangular figure two parallel sides are the same.

This means that together the two sides of the rectangle will increase by:

1 m 30 cm + 1 m 30 cm = 2 m 60 cm.

Next, remember that the perimeter of a rectangle is the sum of all four of its sides.

Therefore, the perimeter of the rectangular shape will also increase by 2 m 60 cm.
