Question

Can someone help me with 9 and 10? I’m really lost— thank you :)

Answer 1

for 9, do 0.5*6*9.2*5 to get the total area of the visual triangles, add that to 0.5*6*4.1*5 to get the area of the pentagon and you should get 199.5 cm^2
for 10, do 0.5*6.9*8*12 to get the total area of the figure and you should get 331.2 cm^2
