Answer:

Its length is 37.5 cm.

Step-by-step explanation:

If two rectangles are similar, their sides are proportional, that is, they have equal ratios. So

The first rectangle has a length of 15 cm and a width of 10 cm. The width of the second rectangle is 25 cm.

So

\frac{15}{10} = \frac{l}{25}

10l = 25*15

Simplifying by 10.

l = 2.5*15 = 37.5

Its length is 37.5 cm.
