attached file

OpenStudy (anonymous):

other side is 20 in.

OpenStudy (anonymous):

2*14+2*20+2*5=78

OpenStudy (anonymous):

my teacher said the answer is 265

OpenStudy (anonymous):

oh sorry i told u the perimeter

OpenStudy (anonymous):

how to get the area?

OpenStudy (anonymous):

yes teacher is correct are=265

OpenStudy (anonymous):

how?

OpenStudy (anonymous):

Area=L*W break Each total into three pieces that are rectangles and add them togethe

OpenStudy (anonymous):

how @Diffeqnofun

OpenStudy (anonymous):

Break the whole figure into 3 rectangles and calculate area by L*w and add the three areas for your total

OpenStudy (anonymous):

@Diffeqnofun I alwaysgot 290

OpenStudy (anonymous):

in the left side rectangle the length is 20 and width is 5 so area of left side ractangle is=20*5=100

OpenStudy (anonymous):

I got that 100 too

OpenStudy (anonymous):

in the right most side rectangle the length =20 and width 6 then area=20*6=120

OpenStudy (anonymous):

Make sure you use 15 *14 for the large rectangle instead of total 20

OpenStudy (anonymous):

in the middle the length is 14-11=3 and width =20-5=15 so area =3*15=45

OpenStudy (anonymous):

now where did you get 15 and 3?

OpenStudy (anonymous):

Also make sure your unit s are square units for area

OpenStudy (anonymous):

add all 100+120+45=265

OpenStudy (anonymous):

in the middle one length= 14-(5+6)

OpenStudy (anonymous):

and width 20-5=15

OpenStudy (anonymous):

do u understand it now

OpenStudy (anonymous):

yes got it.

OpenStudy (anonymous):
