Answer:
Question 8: Area=520in
Question 9: No clue, sorry
Question 12: 300in
Question 11: 400in
Step-by-step explanation:
When you take the area of a figure like question 8, it helps to split the figure into two shapes and take the area of those then add it.
- 11*13= 143 and 29*13=377 377+143=520
Question 11:
A=2(wl+hl+hw)=2·(10·15+2·15+2·10)=400
Question 12:
V=L * W * H
V= 2*10*15= 300in
