Question

find the total cost of making a triangular sail that has a base dimension of 14 feet and a height of 30 feet if the price for making the sail is $20.50 per square foot.
what is the total cost of making the triangular sail?

Answer 1

first find the area of the triangle
A=1/2 (base times height)
Area= 1/2 (14 times 30)
Area= 1/2 (420)
Area=210 ft squared
Then multiply 210 ft by the cost per square foot
210 times $20.50
=$4305
