Decompose that into a rectangle and a right triangle by extending the 6 ft line down to the base. Find the area of both of those figures and add them.

Can you find the base and the height of that triangle? The area will be 1/2 * base * height.
still don'y get it.
you there
anyone that can help
|dw:1359845754154:dw|Understand how we're starting this? Breaking it up into 2 easier shapes :)
yes
|dw:1359845881864:dw|
|dw:1359845947895:dw|
See how the dimensions of the triangle come about? :)
yaa
|dw:1359846112405:dw|So we want to find the area of these two objects separately. Then we'll add those area's together to get the `total area` of the figure.
ok so i got C
Hmm did you forget the formula for area of a triangle maybe? :o
cuz C is too big :c
idk what the answer is then
lol :)
well it feels like you're just guessing :) lol
i multiplide 10 and 7 i got 70 then i multiplide 4 and 2 then i got 16 then i add them together which i got 86
The 70 looks good. \(4 \times 2 \ne 16\) , might wanna visit Mr Calculator for that one! :O And then remember, The area of a triangle we take `half` of the base times height.
woops i ment 8
Cool c: Just remember for a triangle,\[\large A=\frac{1}{2}b\cdot h\]
So we only want half of that 8 c:
hmm
|dw:1359846808816:dw|If we had a square like this, the area would be 8, because 4 x 2 = 8.
|dw:1359846855993:dw|But we have a triangle, which is half of that area.
still confused? <:o
yes
aw :c
ya sorry i'm not that smart
was 74
im sure that's not true c: math isn't for everyone!
ya 74 D:
so is 74 right
yes c:
