A triangular sail has a base length of 2.5 meters. The area of the square is 3.75 square meters. How tall is the sail?

The height of the sail is ##3m##.

The area of a triangle can be calculated as:

##A=1/2xxbxxh##

where ##b## is the length of base and ##h## is the length of height

From the text we see that the area is given ##A=3.75##, the base is given: ##b=2.5##

Our task is to calculate the height ##h##

##A=1/2xxbxxh##

##2A=bxxh##

##h=(2A)/b##

##h=7.5/2.5##

##h=3##

The answer is :

Height of the sail is ##3m##
