Question

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.

Answer 1

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

Answer 2

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
