Question

the length must be greater than _70_ cm

please check if this is correct.
thank you!!

Answer 1

"the length must be greater than _70_ cm" is a feasible but incomplete answer to the question "what lengths" meaning all possible lengths.

The width is 27 cm.
Let the length be L.
then perimeter P>70 is given by
2(27+L)>70
54+2L > 70
2L > 16
L > 8 cm
