Extract C states: 'A key factor in the economic viability of commercial biofuel production is crop productivity. Miscanthus crops are highly productive, yielding on average 1.81.81.8 times as much dry biomass per hectare as traditional switchgrass crops...'
If 666 hectares of land yield 82.882.882.8 tonnes of Miscanthus, calculate, to one decimal place, the expected yield of switchgrass from 141414 hectares of land.
