Question

Need Help With This One Please!!!!

Answer 1

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

Answer 2

Answer: 30 feet.

Step-by-step explanation:

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

$A=\frac{bh}{2}$

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 $A=\frac{bh}{2}$ and solve for the height "h":

$225ft^2=\frac{(15ft)h}{2}$

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

$h=\frac{(2)(225ft^2)}{15ft}$

$h=30ft$
