Question

The expression to find the perimeter of a rectangle is 2(length + width). What is the perimeter, in units, of a rectangle of length fraction 1 over 7 unit and width fraction 1 over 2 unit?

A.fraction 1 and 1 over 7 units

B.fraction 1 and 2 over 7 units

C.fraction 4 over 9 unit

D.fraction 2 over 9 unit

Answer 1

I think it’s B but I’m sorry if it’s wrong


Hope this helps :)

Answer 2

OPTION B

`1(2)/(7)units`

Explanation:

1. You have the following formula for calculate the perimeter of a rectangle:

`P=2(l+w)`

Where l is the lenght and w i the width.

2. Therefore, if the rectangle has the following dimensions:

`l=(1)/(7)units\\\\w=(1)/(2)units`

You can substitute these values into the formula shown above to calculate the perimeter of a rectangle. Therefore, you obtain the following result:

`P=2((1)/(7)units+(1)/(2)units)=(9)/(7)units` or
`1(2)/(7)units`
