How do i find the width and the length of a rectangle when only given the perimeter?

answer:

not given enough info

step-by-step explanation:

if the perimetre they gave you was lets say 12cm, then the width and length of the rectangle would definitely not be 3 cm because that would be a square, so the possible answers would be:

2cm by 4cm

1cm by 5 cm

you just divide the perimetre given by two, and find two numbers that add up to that number, but they cant be the same otherwise it would be a square.

hopefully this

i just took the test, the correct answer is .. 31.5 in.
