Answer:
60% of 25 = 15 and 2.52
Step-by-step explanation:
The area of triangle ABC is the amount of space on the triangle
The area of the triangle is 54.84 square units
<h3>How to determine the area of triangle ABC</h3>
Start by drawing the triangle (see attachment)
Next, calculate the measure of angle B using the following tangent ratio
![\tan(B/2) = \frac 34](https://tex.z-dn.net/?f=%5Ctan%28B%2F2%29%20%3D%20%5Cfrac%2034)
This gives
![\tan(B/2) = 0.75](https://tex.z-dn.net/?f=%5Ctan%28B%2F2%29%20%3D%200.75)
Take the arc tan of both sides
![B/2 = 36.87](https://tex.z-dn.net/?f=B%2F2%20%3D%2036.87)
Multiply by 2
![B = 73.74](https://tex.z-dn.net/?f=B%20%3D%2073.74)
Next, calculate the length of side AD using the following equation
![AD = \tan(B) * BD](https://tex.z-dn.net/?f=AD%20%3D%20%5Ctan%28B%29%20%2A%20BD)
This gives
![AD = \tan(73.74) * 4](https://tex.z-dn.net/?f=AD%20%3D%20%5Ctan%2873.74%29%20%2A%204)
![AD =13.71](https://tex.z-dn.net/?f=AD%20%3D13.71)
The area of the triangle is then calculated as:
![Area = AD * BD](https://tex.z-dn.net/?f=Area%20%3D%20AD%20%2A%20BD)
This gives
![Area = 13.71 * 4](https://tex.z-dn.net/?f=Area%20%3D%2013.71%20%2A%204)
![Area = 54.84](https://tex.z-dn.net/?f=Area%20%3D%2054.84)
Hence, the area of the triangle is 54.84 square units
