Answer:
Step-by-step explanation:
last one is corect because opposite sides of a parallelogram are equal.
If the width is w and the length is l, then 2w=l. In addition, l*w=88200 (using the area formula). Plugging 2w in for l, we get 2w*w=88200=2w^2. Dividing both sides by 2, we get w^2=44100 and w=sqrt(44100)=210.
