Question

you can grow 4 pounds of wheat per square meter of farmland.If you grow 3600 pounds wheat on a square farm, what is the length of the farm?

Answer 1

4 lb per sq m; 3600 lbs yield implies 900 sq m; area 900 = x² where x is the length of the side of the farmland.

Therefore x =√900 = 30 m of square farmland (side length).
