Answer 1

Answer:

34 percentage answer ho ga

Answer 2

Answer:

400 m

Step-by-step explanation:

Step 1

let us say the width is (b)

and length is (l)

And It is given that length is 12% more than its width.

So $l=\frac{100+12}{100} b$

$l=1.12b$

Step 2

Now area pf rectangle is l*b

$448=l*b$

 $448= 1.2b*b\\448= 1.2b^2\\\\Divide by 1.2\\\\\frac{448}{1.2} = \frac{1.2b^2}{1.2} \\\\400= b^2\\\\Taking_Squareroot\\\sqrt{400} =\sqrt{b^2} \\\\20= b$
