Answer: 166 cm^2
Step-by-step explanation:
step 1: 5(4) = 20
step 2: 20(2) = 40 (double it since theres two sides of the same thing; top and bottom)
step 3: 4(7) = 28
step 4: 28(2) = 56
step 5: 5(7) = 35
step 6: 35(2) = 70
step 7: add all the bolded together; 70 + 56 + 40 = 166
there you go, hope it helps! </3
