what is the area of a rectangle with a width of 36cm and a perimeter of 80cm

OpenStudy (barrelracer011):

Well do you know the formula for area?

OpenStudy (anonymous):

no

OpenStudy (barrelracer011):

its length x width

OpenStudy (barrelracer011):

So you need to divide 80 up because it is the full perimeter so you need to subtract 36 from 80, 2 times and then divide that number by 2 and what do you get?
