Answer 2

619,5/3,5=177
177 * 13,25 = 2345,25 рублей

Answer 3

To find the cost of 13.25 meters of fabric, we can use a proportion:

Let's call the cost of 13.25 meters of fabric "C."

We know that 3.5 meters of fabric cost 619.5 rubles.

So, the proportion is:

3.5 meters / 619.5 rubles = 13.25 meters / C

Now, let's solve for C:

C = (13.25 meters * 619.5 rubles) / 3.5 meters

C = 2326.25 rubles

Therefore, the cost of 13.25 meters of fabric is 2326.25 rubles.
