Question

a triangular sail has a base of 5m and a height of 10 m if the canvas costs 18 dollars a square meter, find the cost of canvas to make a sail

Answer 1

$450

Explanation:

Start by finding the area of the triangular sail.

`A=(1)/(2)bh`

Substitute the given lengths into the equation:

`A=(1)/(2)*5*10\\A=5*5\\A=25m^2`

Now, multiply this by 18 dollars per square meter.

`25m^2((18)/(1m^2))=25*18=450`
