then what do i do?
OpenStudy (omarbirjas):
ok lets take a look at the pic
OpenStudy (omarbirjas):
we cut up the shaded region ino 2 parts. a rectangle and a trapazoid.
OpenStudy (omarbirjas):
find the area of both shapes seprately then add.
OpenStudy (omarbirjas):
area of rectangle= 16

now to find the area of the trap. the formual is A=(h(b_1+b_2))/2
OpenStudy (omarbirjas):
the highet is 10, base 1 is 1 and base 2 is 4.
OpenStudy (omarbirjas):
1+4=5
OpenStudy (omarbirjas):
A=(10(5))/2
OpenStudy (omarbirjas):
50/2

25
OpenStudy (omarbirjas):
the area of the trapazoid is 25 and now add it to the area of the rectangle...and you get25+16=41
OpenStudy (omarbirjas):
the area of the shaded area is 41feet^2
OpenStudy (omarbirjas):
now to find the unshaded all we have to do is subtract shaded area from the total area which is 8*16=128
OpenStudy (anonymous):
ok so then the area for the unshaded is 87?
