Best ResponseYou've already chosen the best response.0DO you know how to find the area of triangles and/or trapezoids?

Best ResponseYou've already chosen the best response.0do 17 times 14 and then 18 times 12

Best ResponseYou've already chosen the best response.0well, with this figure you can break it down...so if you know how to find the area of triangles and trapezoids, its not as hard as it looks :)

Best ResponseYou've already chosen the best response.0How would I find the width? {I am horrible with math sorry}

Best ResponseYou've already chosen the best response.0hm? what do you mean?

Best ResponseYou've already chosen the best response.0Because if i break it up the shape at the top would need a height, sorry I meant hieght not width

Best ResponseYou've already chosen the best response.3you have the height of part of the whole shape and and the entire complex shape the trapezoid is just 1712

Best ResponseYou've already chosen the best response.3notice that the height of the triangles is 12 the whole shape's height is 17 that means if you extend the height of the triangle to the end of the shape you get \(12+x=17\)

Best ResponseYou've already chosen the best response.3dw:1432754292136:dw area of a trapezoid = \(\dfrac{a+b}{2}h=\dfrac{14+18}{2}*5=\dfrac{32}{2}*5=16*5=80\) next, we find the area of the triangles

Best ResponseYou've already chosen the best response.0Okay, is 9 the width because it's half of the bottom of the top shape?

Best ResponseYou've already chosen the best response.3that isn't necessary as we'd be adding up the 2 triangles anyways. recall that \(Area(\Delta)=\dfrac{bh}{2}\)

Best ResponseYou've already chosen the best response.3if you don't believe me you can break it up or do it as a whole.dw:1432754774085:dw

Best ResponseYou've already chosen the best response.0oh! okay see I didn't understand what you were saying at first I get it now it would be 108?

Best ResponseYou've already chosen the best response.3mhm 108+the other area is the whole thing

Best ResponseYou've already chosen the best response.3hm? I thought the other area was 80

Best ResponseYou've already chosen the best response.0oh im sorry I thought you meant not to half to triangles and add those

alyssa_xo

Best ResponseYou've already chosen the best response.3oh, you added up the triangle twice the reason I drew it out was because I wanted to demonstrate that you could either take the area of the whole triangle (0.5*12*18=108) or you could do the 2 triangles (0.5*12*9)+(0.5*12*9)=108
