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.

#3.75=1/2*2.5*H#

Next, we can simplify a little.

#3.75=1.25*H#

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

#3.75/1.25=H#

#3=H#
