A scale drawing of the side of a house is shown below. What is the best estimate of the area of the side of the house? Picture will be in the comments

OpenStudy (notamathgenius):

Picture?

y did u delete ur comments..

Wait forget that whole thing up there (cube)6x5x4x6= Triangle) 3x5/2

OpenStudy (anonymous):

ok

@sriramkumar

OpenStudy (notamathgenius):

do you know what to do know and when you find the answers for them both add them together to find the area

OpenStudy (anonymous):

but its not one of the answer choices

OpenStudy (notamathgenius):

Its 725.5 did it ask for anything else? rounding? or what not

OpenStudy (anonymous):

the answers i wrote up there^^

OpenStudy (notamathgenius):

Then something is wrong, hmm well I did all the math right.

OpenStudy (anonymous):

@Notamathgenius can you please clarify me regarding the process of solving this? I'm confused alot with yours, so am asking you please dont mind

OpenStudy (notamathgenius):

The math was for the area of the cube would be 4x6 x 5x6=720 the area of the triangle was 3x5/2

OpenStudy (anonymous):

guys look: 1,000 is the answer.. but idk how to get it

OpenStudy (anonymous):

its just asking for the *side* of the house, which is what confused me at first, you don't need to find the whole cube

OpenStudy (anonymous):

@an12345 Look at it, now the side of the house, has 4 cubes on the vertical line and 5 cubes on the horizontal. so it'll be 4*5 = 20 for the area. Ok till here? now we have area of each cube to be 36, so side will be 6. now multiply 20*6*6 = 720

OpenStudy (anonymous):

wait where did you get the 6 from?

OpenStudy (anonymous):

i've just written 36 as 6*6 thats all :D

OpenStudy (anonymous):

o ok

OpenStudy (anonymous):

how about for the triangle?

OpenStudy (anonymous):

and for it, you have 4 full cubes and two havles... considering them you have 4*36 + 2*26/2 = 180 now adding you get 720 + 180 = 1000 I still dont understand but still i've managed to get it :D ;)

OpenStudy (anonymous):

ohh

OpenStudy (anonymous):

hope you've undertsood this anyways :D @an12345
