Question

What is the perimeter of a rectangle that has a length of 9 cm and a width of 6 cm?

A. 54 sq. cm
B. 54 cm
C. 30 sq. cm
D. 30 cm

Answer 1

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 2

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
