Sagot :

Answer:

$450

Step-by-step explanation:

Start by finding the area of the triangular sail.

[tex]A=\frac{1}{2}bh[/tex]

Substitute the given lengths into the equation:

[tex]A=\frac{1}{2}*5*10\\A=5*5\\A=25m^2[/tex]

Now, multiply this by 18 dollars per square meter.

[tex]25m^2(\frac{18}{1m^2})=25*18=450[/tex]
