Question

A farmer wants to divide his 2700 km2 of land into two separate pastures for his new horses by building a fence that will enclose both pastures. He wants one pasture to be twice the size as the other. What should the dimensions of the larger pasture be if he wants to use the least amount of fencing

Answer 1

All kinds of questions since you don't describe the enclosures.

Do the two fields have the same width?
Are there two disjointed fields with the same width and one length twice the other?
If they are joined by a common width, is that common width included in the total perimeter?

Answer 2

I don't have any additional information except the answer 60km×30km
it's multiple choice question
I used A=xy for the small pasture and A=2xy for the large pasture and added together but can't get the same answer 😥

Answer 3

just a guess, it seems like you are asked about only dimensions of the big one, isnt that just 2/3 of 2700 km2. that is 1800km2 which = 60 km x 20km.
