Five of Lucy's friends decided to split the cost of a $130 birthday gift. Then a sixth and seventh friend decided they also want
to help purchase the gift. About how much less will each of the first five friends have to spend now that two more friends are contributing to the cost of the gift?
The only reason why it is A is because area is just (l x w) or length times width. The length is 9cm and the width is 8cm. If you multiply that, the answer would be 72cm.
