Area = 1/2 * * ht * sum of parallel sides..
OpenStudy (anonymous):
I know, but can you show me step by step. Online school, doesn't do it well. :)
OpenStudy (ganpat):
ok, so what would be parallel sides over here from the figure ??

The bottom and top line? o_o
OpenStudy (ganpat):
yup.. so that would be parallel sides.. and the distance between them will be perpendicular ht..
OpenStudy (anonymous):
By 9 yrds? o_o
OpenStudy (ganpat):
yup..
so A = 1/2 * 9 * (25 + 16)...
OpenStudy (anonymous):
Okay, is the area 738? x_x

how abt 185.4 yd square ??
OpenStudy (anonymous):
How'd you get that? I'm pretty sure I did it correctly. >_<
Please show me step by step solving it. )x
OpenStudy (ganpat):
25 + 16 = 41
41 * 9 = 369
369/2 = 184.5...
OpenStudy (anonymous):
Why'd you divide 369 by 2?
OpenStudy (ganpat):
it says, 1/2 * ht * (sum of parrallel sides)

Yes. but 1/2 is .5? Is it not? Wouldn't that give you the answer 783?
OpenStudy (anonymous):
Hello?
OpenStudy (ganpat):
o.5.. so it will be reduced..
for example, 2*1 =2
2*2 =4
2*0.5 = 1...
OpenStudy (ganpat):
???????????????????????????????????????????????????????????????????????
OpenStudy (ganpat):
still not getting ?
