Delroy’s sailboat has two sails that are similar triangles. The larger sail has
sides of 10 feet, 24 feet, and 26 feet. If the shortest side of the smaller sail
measures 6 feet, what is the perimeter of the smaller sail?
(1) 15 ft (3) 60 ft
(2) 36 ft (4) 100 ft

perimeter of smaller sail
= 6 + (6/10)24 + (6/10)26
= 6 + 14.4 + 15.6
= 36 answer (2)

If the triangles are similar, then each side of one will be in the same proportion to the corresponding side of the other.
This also means that the total of the sides, the perimeter, will be in that same proportion.
What is the perimeter of the larger sail? What is the side-to-side ratio between the triangles (sails)? Multiply the two.

2) 36ft
or...60% of 60 (total perimeter of big sail) I am all about shortcuts

Hi. Pythagoras is your friend. The sides are related because they are all right triangles.
