One sec i need to go check on something but you can write what i need to do! :)
ok see the rectangle that is 8 by 2?
@Chumpian sorry I'm back i needed to go clean some stuff
all good :)
K what do i do?
ok so do you see the rectangle that is 8 by 2?
what is the area of it?
you know its height is 1 but what is it's length?
ok good so the area is?
10? cause 10 • 1 = 10?
now all we have left is the triangle
what is the length and height?
10 by 3
oh wait..... we are finding area not perimeter lol my bad forget the Pythagorean theorem. sry about that xD
what is the formula for the area of a triangle?
\[A = 1/2(b \times h)\]
Lol i really don't understand this question.....
ok well take it one step at a time whats the area of the triangle?
Um i don't know how to do area of triangles yet..... :c
ok so whats the base and the height?
10 and 3
ok so in the equation you multiply them whats 10 times 3?
10 times 3 =? lol
ok then multipled by 0.5? or whats half of 30?
ok Good :) now we add together all the areas
whats 10 + 16 +15?
ok good :) thats the answer to the first part
the second part wants the area of the non-shaded region
whats the area of the entire rectangle?
whats 16 times 8?
thats the area of the entire rectangle
ok so then do i subtract 41 by 120
now all we have to do is subtract the non-shaded region from the shaded region
128 - 41 is?
are you sure :P
128 not 120
Its 87 for the real number
Yep 87 is your answer for part 2 :)
Ok so what should i say on the essay?
hint: the shaded region can beviewed like below: |dw:1437754376090:dw|
Thanks @Michele_Laino but we already finished it!
Yes it is an essay.............
Well you would say the shaded region has an area of 41 ft squared and the non-shaded region has an area of 87 ft squared?
Is that what your looking for?
I just said the things that we said together like this The area of the shaded region is 41 feet. The area of the non-shaded section is 87 feet. • • \_____/
It would have been better if you added ft squared not just ft
ok then ill do that
