All of the answers please :)

Answer 1

Question 8: Area=520in

Question 9: No clue, sorry

Question 12: 300in

Question 11: 400in

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
