x= -3
Answer:
8 cm and 9 cm
Step-by-step explanation:
Those are they only numbers that aren't equal to or less than the third side.
The perimeter is 500 cm, meaning the width + width + length + length is 500 cm in this rectangle.
clearly, since their sum is 500 total, the length of any of the sides cannot be larger than 500, it has to be less to allow room for the other 3 sides. L < 500.
and the length cannot be 0 either, because if it's, then there's no rectangle :). L > 0
L < 500 and L > 0 0 < L < 500.
