Another way which may be easier....first find area of this:

Answer 6

I don't know the formula for this shape.

Answer 7

which shape? trapezoid or triangle?

Answer 8

trapezoid

Answer 9

here u go :)

Answer 10

i dont understand what a b or h is

Answer 11

do you add up the number of squares in the shape?

Answer 12

no, a, b and h are dimensions of a trapezoid respectively.

well if u don't want to use the area formula, then yes, u can add up the no. of squares inside.

Answer 13

i got 27

Answer 14

did u calculate or count?

27 is slightly off by my calculation...

Answer 15

count

Answer 16

yes, its off cuz' its difficult to count those less than half squares...

wuld u like to try using the formula? i will help....look at the pic n see if u know what a, b and h are in this case

Answer 17

i dont know how you find out what a b and h are

Answer 18

b=8
a=6
h=10

Answer 19

if u dont mind, count again plz?

Answer 20

aw man okay

Answer 21

i count b=9...

Answer 22

wait according to your site, a=b and b=a, you have h right though.
a=6
b=5
h=3
this time i just counted the whole squares. I didn't count the squares with a bit of the square missing. I hope you understand what I am saying. wait a minute your including the trangle, thats why okay. im not including the triangle.

Answer 23

okay let me do it your way hold up

Answer 24

counting the square will be difficult....much easier to calculate by finding out what a, b, h are....

Answer 25

a=9
b=6
h=5

Answer 26

okay i included the triangle, is this right?

Answer 27

yes - first include it then subtract the triangle area out to get the right ans :)

Answer 28

i got 37.5

Answer 29

wait wait wait back up....wuld u like to try using the formula to calculate the area; instead of counting boxes? plz?

Answer 30

u will always be off a lil because of the less than half squares if u count :(

Answer 31

haha i didnt count the boxes though, its a+b/2*h right?
therfore being (9+6)/2*5=37.5

Answer 32

okay tell me, what am i doing wrong??

Answer 33

:) ALRIGHT, Norma!

ur b is off by one...so the area should be ((9+7)/2)*5=40

Answer 34

except for missing 1 on one side, ur work was perfect :P

Answer 35

now all u need is to find triangle area n subtract that from 40; that will be ur ans. good luck!

Answer 36

are of a triable is 1/2 b*h, right?

Answer 37

correct!

Answer 38

i got 7.5 for the area of a triangle, and when i subtract 7.5 from 40 i get 32.5.

Answer 39

show whats b and h for triangle plz?

Answer 40

b=5
h=3

Answer 41

h...try count again plz?

Answer 42

okay, maybe its only four
