#### Answer

The length of the other two sides is less than or equal to 8 cm.

#### Work Step by Step

The perimeter is less than or equal to 24cm.
p≤24 ⟶ substitute the given lengths and let s be the unknown side
2s+8≤24 ⟶ subtract 8 from both sides
2s+8−8≤24−8 ⟶ simplify
2s≤16 ⟶ divide both sides by 2
2s÷2≤16÷2 ⟶ simplify
s≤8
