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 cm
D. 30 sq. cm

Answer 1

Answer: d.30cm

Explanation:

the formula for perimeter is P=2L+2W

Substitute the length and width

P= 2(9)+2(6)

Multiply

P= 18+16

Add

P=30

Add the unit

P= 30cm

Answer 2

The answer is option C

Explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question

l = 9 cm

w = 6 cm

Substitute the values into the above formula and solve

We have

P = 2(9) + 2(6)

= 18 + 12

We have the final answer as

P = 30 cm
