20. How many bags of grass seed were used for rectangular lawn X ?
(1) Lawn X has a perimeter of 720 feet.
(2) One bag of grass seed was used for each 5,000 square feet of lawn X

The answer is c but it doesn't make sense.How genius should a person be to find the area only from perimeters?

If a rectengular has sizes of a and b,(I) says that a+b is 360.How can we find the area of rectengular?

Hey,

I also think that the answer should be "E"
As you stated, we can not find the area of the lawn and thus
we can't find how many bags were used.
