Joe wants to carpet a 12 foot by 18 foot rectangular living room and a square bedroom. one side length of the square bedroom is 12 feet. carpet costs $3.50 per square foot. what percent of the total amount joe will pay will be spent on carpeting the bedroom? show your work

Area=legnth times width
in square, length=width

area living rom=12 times 18=216
area square bedrwoom=12*12=144

total=216+144=360
we don't actualy need to find the money value
bedroom/total=144/360=0.4=40/100=40%

40% spent on the bedroom

if you don't believe me
360*3.50=1260
bedroom=144*3.50=504
504/1260=0.4=40/100=40%
