Answer: 30 feet.

Explanation:

The formula used to calculate the area of a triangle is:


A=(bh)/(2)

Where "b" is the base and "h" is the height.

In this case you know that the area of this triangle is 225 ft² and its base is 15 ft. Then, you can substitute these values into the formula
A=(bh)/(2) and solve for the height "h":


225ft^2=((15ft)h)/(2)


(2)(225ft^2)=(15ft)h


h=((2)(225ft^2))/(15ft)


h=30ft

For this case we have that by definition, the area of a triangle is given by:


A = \frac {1} {2} b * h

Where:

b: It's the base

h: It's the height

Substituting the values, according to the given data:


225 = \frac {1} {2} (15) * h\\225 = 7.5h

Dividing between 7.5 on both sides of the equation:


h = \frac {225} {7.5}\\h = 30

Thus, the height of the triangle is 30ft

Answer:

30ft
