The length of a rectangle is 24 units. Can the perimeter x of the rectangle be 60 units when its width y is 11 units?

OpenStudy (anonymous):

Perimeter = 2(length) + 2(width) so check by substituting.

|dw:1384181287887:dw| perimeter is all the way around

OpenStudy (anonymous):

So the equation would be \[24^{2}+11^{2}=70

OpenStudy (unklerhaukus):

that is not the right formula, use Easyaspi314 's formula above

OpenStudy (anonymous):

oh ok thanks

OpenStudy (anonymous):

the answer would be yes because 2(24)+2(11)=60

OpenStudy (unklerhaukus):

right
