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
