Question

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

Answer 1

Answer:

$\huge\boxed{1 \frac{4}{5}\ \text{ft}}$

Explanation:

Change $\frac{1}{5}$ so that is has a common denominator.  $\frac{1*2}{5*2}=\frac{2}{10}$

Make an equation.  $\frac{7+7+2+2}{10}$

Add.  $\frac{14+4}{10}$

Add.  $\frac{18}{10}$

Divide both sides by 2.  $\frac{9}{5}$

Convert to a mixed number.  $1 \frac{4}{5}$

Answer 2

Answer:

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.
