Question

just solve this guy's.......

Answer 1

$\text{Side ratio of photo and card left over}\\\\ = \frac{10}{15} \\\\= \frac {2}{3}$

The diagram shown below have a length

Let it be (x+y)

Here the question gives us a idea that the photo and the piece of card left is similar

Now ,

$\\ \frac{2}{3}=\frac{16}{y}\\ y = 16 \times \frac{3}{2}\\y =\cancel{16}\times\frac{3}{\cancel2}\\y=8\times 3\\y=24 cm$

Now we get 'y'

Now

Total length of card = 30 = (x+y)

$\\x=30-y\\x=30-24\\x=6 cm$

$\underline{ Answer}$

$\boxed{\implies x=6cm}$

Answer 2

Copy the above answer.....
