The landscaper must build another rectangular patio with the least perimeter possible using 9 1-foot-square tiles. What should be the dimens

OpenStudy (anonymous):

hmmm, well intuitively it seems like the rectangle with the least perimeter would be a square

OpenStudy (anonymous):

since that ensures the most edges are covered (which in aggregate are the perimeter)

OpenStudy (anonymous):

so that would be 3x3, so 12 foot perimter

OpenStudy (anonymous):

another way to look at it, how many rectangles can be made

OpenStudy (anonymous):

1x9 is one

OpenStudy (anonymous):

3x3 is the only other

OpenStudy (anonymous):

1x9 has a 20 foot perimeter (9 + 9 + 1 + 1)

OpenStudy (anonymous):

3x3 has a 3+3+3+3 = 12 perimeter

OpenStudy (anonymous):

so again 3x3 is the one with the least perimeter

OpenStudy (anonymous):

Thank you I have another question, can you help me

OpenStudy (anonymous):

sure but I'd say ask another one to keep them separate

OpenStudy (anonymous):

kk see it

OpenStudy (anonymous):

hmm, ask a different question lol

The perimeter of a paved area being built at a playround is going to be 46 meters. If the length and width are each a whole number of meters, what should the length and widht of the area be to cover the greatest possible area? draw a picture and make an organized list to solve.
