The perimeter decreases by 4. Decreasing the length by 4 decreases the perimeter by 8. Increasing the width by 2 increases the perimeter by 4. -8+4=-4

For example: Area of a rectangle could be: 8 x 6 (8 being the length and 6 being the width). The perimeter is 8+8+6+6=28

If the length is decreased by 4 then it becomes 4 If the width is increased by 2 then it becomes 8.

The perimeter becomes 4+4+8+8=24
