Find the total cost of making a triangular sail

Question

Find the total cost of making a triangular sail that has a base dimension of 15 feet and a height of 20 feet if the price for making the sail is $17.50 per square foot.

Answer 1

base = 15 feet

height = 20 feet

 

 

Plug in these values to find the area of the triangular sail.

 

Area = (base * height) / 2

 

 

Then calculate the total cost.

 

Total cost = 17.50 * Area

Answer 2

Hi Becky, 

Step One: Find the area of the triangle

Triangle Area= (1/2)(base)(height)

Triangle Area=(1/2)(15)(20)

Triangle Area=150

Step Two: Calculate the total cost

Total Cost= (Cost of one foot)(Triangle Area)

Total Cost= (150)(17.50)

Total Cost=2625

∴It costs $2625 to make the triangular sail.
