find the perimeter and area of that

OpenStudy (anonymous):

do you know how to find the perimeter? Use the formula below. P = (w+l)*2

OpenStudy (anonymous):

wht does I stand for

OpenStudy (anonymous):

how did u get that

OpenStudy (anonymous):

well, it's P=2 * (2b+2b+3)

OpenStudy (anonymous):

@robtobey and @sourwing

OpenStudy (anonymous):

@hartnn help

OpenStudy (anonymous):

P=2(b) + 2(b+3) P=2b+2b+6 P=4b+6

OpenStudy (anonymous):

do u get it?

OpenStudy (anonymous):

yup

OpenStudy (anonymous):

do you need help with the area?

OpenStudy (anonymous):

|dw:1396990475795:dw|

OpenStudy (anonymous):

how about that i got (x+3) (x+3) (x-2)

OpenStudy (anonymous):

for perimeter it will be P=2(x+3)+2(x-2) P=2x+6+2x-4 P=2x+2x=6-4 P=4x=2

OpenStudy (anonymous):

soory it's a typo in the last line of my previous response, it's actually supposed to be P=4x+2
