A rectangular patch of grass at the park is 17 yards long and 10 yards wide. What is the area of the patch of grass?

OpenStudy (anonymous):

i got 170

OpenStudy (youngstudier):

170 is correct ^_^

OpenStudy (anonymous):

i ahve another one for u to check

OpenStudy (youngstudier):

ok, ask away

OpenStudy (anonymous):

OpenStudy (youngstudier):

What'd you get?

OpenStudy (anonymous):

i got 96 if that correct

OpenStudy (youngstudier):

no, I'll explain this to you ok?

OpenStudy (anonymous):

k

OpenStudy (youngstudier):

We'll make it into two rectangles. Let's find the area of the top one. 14*4=?

OpenStudy (anonymous):

56

OpenStudy (youngstudier):

Right, now, for the bottom one we do 12-4 first, do you know why?

OpenStudy (anonymous):

no why

OpenStudy (youngstudier):

because if you cut them into two seperate rectangles, the side length for the bottom rectangle will not be 12, so we take away the 4 which originally made it 12 to get the new side length, does that make sense?

OpenStudy (youngstudier):

I suppose that's a rather confusing explanation, isn't it?

OpenStudy (anonymous):

no not at all

OpenStudy (youngstudier):

Ok, so do 12-4=?

OpenStudy (anonymous):

8

OpenStudy (youngstudier):

ok, so now, do 8*8=?

OpenStudy (anonymous):

64

OpenStudy (youngstudier):

Right, now add 64 and 56, what do you get?

OpenStudy (anonymous):

120

OpenStudy (youngstudier):

Correct! ^_^

OpenStudy (anonymous):

last one ready

OpenStudy (youngstudier):

Yup, but open a new question and tag me, k?
