Look here..

Answer 3

break it into parts. the middle is a square, so b*h. 8*4=32 for the middle part.
the sides are 1/2b*h because they are triangles. they are both 1/2(2)(4), so each are 4. 32+4+4=40cm is your answer.

Answer 4

or do what he said, (8+12)/2 = 10. times the height, 10*4=40

Answer 5

not one of my options

Answer 6

my options are 10
44
48
and 20

Answer 7

im so positive its 40...

Answer 8

math looked good but its not a option :(

Answer 9

Area of a trapezium = \[1/2 h(b_1+b_2)/2 \]

Answer 10

So use SOHCAHTOA to find the base of the other triangle and then add that to 2cm and 8cm to get the total length of the lower base.

Answer 11

if i use the formula u just gave me i get 20

Answer 12

its 40. you dont divide by 2 twice. im 100% sure its 40.

Answer 13

oh well im off for the night... good luck with it, but im sure its 40 haha

Answer 14

1/2(4)(8+12)/2

Answer 15

You cannot assume that the base of the other triangle is 2cm

Answer 16

Hint: Use tan to get the base if the right triangle on the left. Tan45=1 and tan=opp/adjacent

Answer 17

base of*

Answer 18

oh and I made a typo. You should only have one (1/2) not two so it's
\[1/2(b_2+b_1)h\]

Answer 19

Your answer should be 44, let me know if you still need help.
