OpenStudy (michele_laino):
ok!
OpenStudy (michele_laino):
then we have four triangles. The area of each triangle is:
(4*6)/2=...
OpenStudy (rebeccapink6398):
12+16?=28
OpenStudy (michele_laino):
no, since we have four triangle, so the requested area is:
(4*12)+ 16=...?
OpenStudy (michele_laino):
triangles*

OpenStudy (rebeccapink6398):
what? 4*12? why
OpenStudy (michele_laino):
since the area of each triangle, is 12, and we have four of such triangles, so the total lateral area is:
4*12
OpenStudy (rebeccapink6398):
so then 48+16?
OpenStudy (michele_laino):
that's right!
OpenStudy (rebeccapink6398):

ok!
OpenStudy (rebeccapink6398):
yay! so i think do we do as before in the last question?
OpenStudy (michele_laino):
as for previous exercise, we have the base whose side is 32 inches, so the corresponding area is:
32*32=...?
OpenStudy (michele_laino):
yes! we have to do as in the last question
OpenStudy (rebeccapink6398):
ok :D and i got 1024 and thennn we umm times the base and triangles?

okay i think i did it right? I got D
OpenStudy (michele_laino):
yes!
we have four triangles, and the area of each of them is:
(32*36)/2=...?
OpenStudy (michele_laino):
is the question clear?
OpenStudy (rebeccapink6398):
yes and yay! okay one last question if you dont mind? :)
OpenStudy (rebeccapink6398):

OpenStudy (rebeccapink6398):
i think it may be 7
OpenStudy (michele_laino):
ok!
OpenStudy (michele_laino):

36.....36*2=72
OpenStudy (michele_laino):
that's right!
OpenStudy (michele_laino):
then we have two rectangles, and the area of each of them is:
4*7=...?
OpenStudy (rebeccapink6398):
28...28*2=56
OpenStudy (michele_laino):
ok! Finally we have two rectangles, and the area of each of them is:
7*9=...?

63....63*2=126
OpenStudy (michele_laino):
that's right!
So, the requested area is given by the subsequent computation:
72+56+126=...?
OpenStudy (rebeccapink6398):
