Question

A 200m x 80m field produces 4800kg of harvest. How mcuh harvest will be produced by a 190m x 90m field?

Answer 1

16000 m^2 field produces 4800 kg of harvest;
17100 m^2 field produces x kg of harvest;

16000 / 171000 = 4800 / x ;
160 / 171 = 4800 / x ;
x = ( 171 * 4800 ) / 160 ;
x = 5130 kg ;
