Answer:

d) 30 cm

Explanation:

P = 2 (l + w)

P = 2 (9 + 6)

P = 2 (15)

P = 30

30 sq. cm woul'd be wrong because that's indicating the area (you don't use sq. when finding perimeter)

Answer:

D. 30 cm

Explanation:

A rectangle has two of the same sides and two of another length so it would be 9+9+6+6, which is 30
