OpenStudy (rational):

doesn't look correct

OpenStudy (rational):

the figure is made up to two pieces : 1) rectangle 2) triangle

OpenStudy (anonymous):

DO I multiply all of them

OpenStudy (rational):

find each area and add up

OpenStudy (rational):

look at rectangle, its width = 14 length = 21 so area = ?

OpenStudy (anonymous):

294

OpenStudy (rational):

Yes! thats the area of rectangle, save it.

OpenStudy (anonymous):

ok

OpenStudy (rational):

next look at triangle : base = 21-12 = 9 height = 16 so area = ?

OpenStudy (anonymous):

144

OpenStudy (anonymous):

so 438

OpenStudy (rational):

careful, area of triangle formula os 1/2*b*h

OpenStudy (rational):

looks you forgot to divide by 2 for triangle

OpenStudy (anonymous):

so 72 + 294

OpenStudy (rational):

Yes!

OpenStudy (anonymous):

so 366

OpenStudy (anonymous):
