Xy= 540
y= 5x/3
x(5x/3)=540
5x^2/3=540
1630=5x^2
x=sqrt(1620/5) = sqrt(324)= 18
x= 18yd
y=30yd
answer: 18 x 30 yards

oranges
number of oranges to cost=5:2
find the cost of 2 dozen (24) oranges
number of oranges to cost=5:2
5:2=24:?
5/2=24/?
times both sides by 2 times ?
5 times ?=48
divide both sides by 5
?=9.6
2 dozen oranges costs $9.60
this one I can't see how many days
but for x days, the cost is x times $60
