A rectangle has a perimeter of 12 m.if each side is a whole number of meters,what are the possible dimensions for the length and width?List them and explain your answer.
for a rectangle the perimeter is 2(L+w) where l is length and w is width if perimeter is 12 l and w have to equal 6 because 6 * 2 =12 answers (l+w) 3,3 2,4 4,2 1,5 5,1 because you can have each number represent the length and width
1 and 5 2 and 4 3 and 3 the two widths have to be the same also the length. a square can be a rectangle not the other way around that is why 3 by 3 works and those 3 can be flipped to make 5
