The sail is 3 meters tall.


The following formulas is used to find the area of a triangle.

#A=1/2 *B*W#

B is the length of the base of the triangle.
H is the length of the height.

In this problem, we are giving A and B. We are looking for H. All we need to do is plug in the values that we have.


Next, we can simplify a little.


Finally, we simply isolate the variable H by moving all numbers to the other side.
