Answer:

$3,075

Step-by-step explanation:

Given, for a triangular sail (assuming its a right triangle)

base dimension = 15 feet

height = 20 feet

Area of sail,

= area of right triangle

= 1/2 x base x height

= 1/2 x 15 x 20

= 150 ft²

we are given that the price per squre foot is $20.50

hence cost of sail

= price per square foot x area of sail

= $20.50 x 150 ft²

= $3,075
