Answer 1

40 inches is the answer

Answer 2

In this question , it is given that , the width of a rectangle is 6 2/3 inches.The length of the rectangle is twice its width.

First we need to convert mixed fraction to improper fraction.

`width = 6 (2)/(3) = (20)/(3)`

And length is twice of width, so length is

`length = 2* (20)/(3) = (40)/(3)`

The formula of perimeter is two times the sum of length and width.

`Perimeter = 2((20)/(3) + (40)/(3) ) = 2( (60)/(3)) = 2*20 = 40 inches`
