which part is shaded? is it the shape with orange lines around it ?

OpenStudy (anonymous):

yeah the orange is the shaded white isnt

OpenStudy (anonymous):

wait

OpenStudy (anonymous):

ok wow the picture looks diffrent the way it sent

OpenStudy (anonymous):

the grey is the not shaded the area in the orange is

OpenStudy (phi):

ok. It seems easier to me to find the grey part first and we can find the area of the big rectangle. and the orange part is whole - grey part

OpenStudy (anonymous):

ok

OpenStudy (phi):

start by drawing in lines to make "simple figures" |dw:1427375804355:dw| can you label as many "lengths" as possible in the figure ?

OpenStudy (anonymous):

i dont understand what your asking

OpenStudy (phi):

The original picture labeled some of the lines The job is to start with those numbers, and try to label as many of the lines as possible.

OpenStudy (phi):

for example, what are the lengths of the tiny square in the middle ?

OpenStudy (anonymous):

2 feet

OpenStudy (phi):

so label all 4 sides 2

OpenStudy (phi):

and inside the square you can put its area, which is 2*2= 4

OpenStudy (anonymous):

ok

OpenStudy (phi):

what about the rectangle on the very bottom and to the left. can you figure out the lengths of each of its 4 sides ?

OpenStudy (anonymous):

well the sides are 2 feet

OpenStudy (phi):

yes. what about the top?

OpenStudy (anonymous):

but the other two are bigger than 8 so i would say 10 feet
