Quizplus · Accepted Answer

Consumer surplus is the area of the triangle below the demand curve and above price. The area of any triangle is equal to ½(b × h), where b = base and h = height. So here, if the government requires cheese to be sold for $8 per pound, consumer surplus would equal ½(20 × 2)= $20. Note that this is less than consumer surplus at the market equilibrium price of $6 per pound.
