The distance between the target and the edge of the football field is 9ft.
What does this mathematical problem require?
This mathematical problem requires you to calculate the distance between the target and the edge of the football field or the height of this imaginary triangle (distance between the vertex and the base).
How do you determine the height of a triangle?
The first step is to find the total area of the triangle, the following formula is used:
- s = a + b + c/2
- s = 15 + 15 + 24/2
- s = 54/2
- s = 27
Now, apply this formula:
- A = √s(s - a)(s - b)(s - c)
- A = √27(27 - 15)(27 - 15)(27 - 24)
- A = √27·12·12·3
- A = √11664
- a = 108 ft2
Finally, use the following formula:
- H = 2 x a / b
- H = 2 x 108 / 24
- H = 216/ 24
- H = 9 ft
