To find the unit price of each bag, divide each cost by the weight to find the cost of shrimp per pound.
For the 2.12 pound bag: 14.75 / 2.12 = $6.96 (rounded to the nearest cent)
For the 3.77 pound bag: 24.99 / 3.77 = $6.63 (rounded to the nearest cent)
You can tell that buying the 3.77 pound bag is better based on the unit price because of 6.63 < 6.96.
Finding the lengths of the legs of the right triangle, we have 6 and 3. (6*3)/2 = 9. Finding the area of the semi-circle we obtain
which rounding to 3.14 as pi, we obtain 3.5325. Adding up the area of the triangle and the semi-circle and the triangle we get 9+3.5325 which equals 12.5325
