Given,
Area = 225 yd²
Base = 30 yd
Height = [To be calculated]
To find:
The height of the given triangle.
We know that, area of a triangle is:
![\frac{1}{2} \times (b \times h) \\ \\ \leadsto \frac{1}{2} \times (30 \times h) \\ \\ \leadsto \frac{1}{2} \times 30h \\ \\ \leadsto \frac{1}{ \cancel{2}} \times \cancel{30}h \\ \\ \leadsto1 \times 15h \\ \\ \leadsto \: h = 15 \: yd](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%20%28b%20%5Ctimes%20h%29%20%5C%5C%20%20%5C%5C%20%20%5Cleadsto%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%20%2830%20%5Ctimes%20h%29%20%5C%5C%20%20%5C%5C%20%20%5Cleadsto%20%5Cfrac%7B1%7D%7B2%7D%20%20%20%5Ctimes%2030h%20%5C%5C%20%20%5C%5C%20%20%5Cleadsto%20%20%5Cfrac%7B1%7D%7B%20%5Ccancel%7B2%7D%7D%20%5Ctimes%20%20%5Ccancel%7B30%7Dh%20%5C%5C%20%20%5C%5C%20%20%5Cleadsto1%20%5Ctimes%2015h%20%5C%5C%20%20%5C%5C%20%20%5Cleadsto%20%5C%3A%20h%20%3D%2015%20%5C%3A%20yd)
Therefore, the require height is 15 yd.

To represent the change in points, you can think of it in two ways:
1. You will go down 25 points for every wrong answer, so -25 + -25 + -25 would represent what is happening. They are all negative, so you keeping moving down in value.
2. You can also think of this as 3 groups of -25.
Both answers are -75. The answer is negative because the change was down in points.
-75 is the integer that represents this situation.
