Question

The length of a rectangle is twice is breadth if the length is 18cm,what is the perimeter of the rectangle

Answer 1

Answer:

L = 2B

18 = 2B [ L = 18 )

B = 18÷2

B = 9

P = 2 L + 2B

= 18×2 + 2 × 9

=36+18

= 54 cm

Therefore, perimeter is 54 cm

Answer 2

Step-by-step explanation:

Let the breadth be b

Then length be 2b

A/q

2b = 18

b =18/2 =9

Therefore the breadth is 9cm

Hence perimeter is 2(9+18)=2*27 =54 cm
