Find the area of the image below: CAN SOMEONE PLEASE EXPLAIN THIS TO ME???? MEDAL WILL BE GIVEN!!!

OpenStudy (anonymous):

umm...need the image

OpenStudy (anonymous):

Gimme a sec

OpenStudy (anonymous):

A.) 41 Square Units B.) 44 Square Units C.)52 Square Units D.)56 Square Units

OpenStudy (anonymous):

break it up into two shapes

OpenStudy (anonymous):

find the area of the square and the area of the triangle then add them together

OpenStudy (astrophysics):

Area of square = a^2 Area of triangle = 1/2*b*h

OpenStudy (anonymous):

Ok, but how do i find the area if there are no numbers?

OpenStudy (astrophysics):

\[A _{s} =a^2\] \[A _{t}=\frac{ 1 }{ 2 }bh\]

OpenStudy (anonymous):

the units are the numbers, count the squares inside the shapes

OpenStudy (astrophysics):

Well I'm not sure of the exact question, since it requires a log in.

OpenStudy (anonymous):

d to e is how many squares?

OpenStudy (anonymous):

its ok @Astrophysics i have an account so I'm able to see the question

OpenStudy (astrophysics):

But it seems you're in good hands @ninjasandtigers will help you :)

OpenStudy (anonymous):

I certainly will :D

OpenStudy (anonymous):

4

OpenStudy (anonymous):

right and how many squares from d to c

OpenStudy (anonymous):

4

OpenStudy (anonymous):

so 4*4 will be the area of the square

OpenStudy (anonymous):

then you need to find the area of the triangle and add the two areas together

OpenStudy (anonymous):

so 16 is the area of the square?

OpenStudy (anonymous):

yup

OpenStudy (anonymous):

and 16 for the area of the triangle? So would it be 16+16

OpenStudy (anonymous):

no

OpenStudy (anonymous):

from B to C its 6

OpenStudy (anonymous):

from B to A its 10 right?

OpenStudy (anonymous):

|dw:1405478063626:dw|

OpenStudy (anonymous):

b to x will be 10, i put in x so it is easier to look at

OpenStudy (anonymous):

what would x to a be

OpenStudy (anonymous):

like on a grid?

OpenStudy (anonymous):

yup :)

OpenStudy (anonymous):

did you figure it out? @monet0223

OpenStudy (anonymous):

sorry, but on a grid it would be (6,5) right?

OpenStudy (anonymous):

so a (6,0) b(-4,5) and c(6,5)

OpenStudy (anonymous):

@ninjasandtigers was i right?

OpenStudy (anonymous):

ok so from 6 to 5 is how many units

OpenStudy (anonymous):

@monet0223

OpenStudy (anonymous):

a to x is 5 units so use the triangle area formula of 1/2bh. so it would look like 1/2(5)(10) then add that answer to 16 and you will have your answer @monet0223
