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

[tex]A = \frac {1} {2} b * h[/tex]

Where:

b: It's the base

h: It's the height

Substituting the values, according to the given data:

[tex]225 = \frac {1} {2} (15) * h\\225 = 7.5h[/tex]

Dividing between 7.5 on both sides of the equation:

[tex]h = \frac {225} {7.5}\\h = 30[/tex]

Thus, the height of the triangle is 30ft

Answer:

30ft

Answer: 30 feet.

Step-by-step explanation:

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

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

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 [tex]A=\frac{bh}{2}[/tex] and solve for the height "h":

[tex]225ft^2=\frac{(15ft)h}{2}[/tex]

[tex](2)(225ft^2)=(15ft)h[/tex]

[tex]h=\frac{(2)(225ft^2)}{15ft}[/tex]

[tex]h=30ft[/tex]
