5:3 = 50:30
so, even using the whole 50cm length, the pennant can only be 30cm wide
To use the whole 36cm width, you'd need a 60cm length, since 5:3 = 60:36
A pennant has a length-to-width ratio of 5:3. What is the length and width of the largest pennant that can be cut from a piece of cloth measuring 50 cm by 36 cm?
