Question

The length of a rectangular is 7/10 ft .and the width is 1/5ft what is the perimeter

Answer 1

1 4/5 ft.

Step-by-step explanation:

Change 7/10 into 70

Change 1/5 into 20

( It will be easier to find perimeter this way )

Formula: P=2(l+w)

P=2(l+w)=2·(70+20)=180

Then, you change the 180 back into a fraction to get 1 4/5.

Answer 2

`\huge\boxed{1 (4)/(5)\ \text{ft}}`

Step-by-step explanation:

Change
`(1)/(5)` so that is has a common denominator.
`(1*2)/(5*2)=(2)/(10)`

Make an equation.
`(7+7+2+2)/(10)`

Add.
`(14+4)/(10)`

Add.
`(18)/(10)`

Divide both sides by 2.
`(9)/(5)`

Convert to a mixed number.
`1 (4)/(5)`
