Taking that in each set there is 5 1-cent coins, 2 20-cent coins and. 1 50-cent coin, Amount in each set = 5(0.1) + 2(0.2) + 1(0.5) =$1.40 Number of sets = $168/$1.40 = 120 sets Total value of 20-cent coins = 120 (0.2) (2) = $48

Area = 9 x 16 - (3 x 4) - (3 x 8) = 144-12-24 = 108 Perimeter = 2 x (9 + 16) + (4 x 4) = 50+16 = 66 The units depends on the questions i use base on the boxes. I hope my answer helps you.
