Answer: The change in area is a reduction of 1/4 (one-fourth) of the original area
Step-by-step explanation:
When each side length of a parallelogram is multiplied by 1/2 , it essentially means that both the length and width of the parallelogram are halved.
Initially, the parallelogram has a length of 9 mm and a width of 5 mm, resulting in an area of 45 square millimeters.
After halving both the length and width, the new dimensions become 4.5 mm for the length and 2.5 mm for the width.
To find the new area, we multiply the new length by the new width, resulting in an area of 11.25 square millimeters.
