Since the two tents are similar in shape that means that the ratio of side to width is the same. we can solve this by finding the ratio of their old tent and then using that to deduce the width of the new tent:

Old tent ratio: sides/width = 10/15

New tent ratio: sides/width = 16/?

10 . 16

-- = --

15 . .x

cross multiply and you get 10x = 15*16

solve for x to get x=(15*16)/10 =**24 ft**
