$16.88, $2.81, $19.69

Consumer surplus is equal to the area below the demand curve and above the market price.
Consumer surplus = 1/2 * base * height = 1/2 * (Q1 - 0) * (P3 - P2) = 1/2 * 3.75 * 9 = $16.88

Producer surplus is equal to the area above the supply curve and below the market price.
Producer surplus = 1/2 * base * height = 1/2 * (Q1 - 0) * (P2 - P1) = 1/2 * 3.75 * 1.5 = $2.81

Economic surplus is the sum of consumer surplus and producer surplus.
Economic surplus = consumer surplus + producer surplus = 16.88 + 2.81 = $19.69
