Answer:
4(5) -7
Step-by-step explanation:
4(5) -7

Answer:
Perfect! I am also learning surface area too! The answer is 168!
Step-by-step explanation:
The formula is:
surface area = base squared plus 4 times (base times height divided by 2)
sa = 6 squared plus 4 times (6 times 11 divided by 2)
sa= 36 plus 4 times 3 times 11 (because divide 6 and 2 and you get 3)
sa= 36 plus 4 times 33
sa = 36 plus 132
sa = 168
I hope this helped. Sorry if I was wrong.
= 144
