A developer can buy a plot of land 90yd x 50yd for $15,000 or a plot of land 180yd x 100yd for $55,000. If all other things are equal, which is the better buy? Why?

90 x 50 = 4500 yd²
@ $15,000, this is $3.33 / yd².
180 x 100 = 18000 yd²
@ $55,000, this is $3.06 / yd²
The 180 x 100 is the better buy  cheaper per yd²
