Question
In the previous question, if the length of each side of the shaded square is 12 cm, what is the total area of the four white triangles?
- 196
- 145
- 180
- 160
The correct answer is: 180
To find the total area of the four white triangles, if the length of each side of the shaded square is 12 cm.
Total area of the four white triangles = 12x + 36 = 12
12 + 36 = 144 + 36 = 180 square cm.
Therefore, the total area of 4 white triangles is 180 square cm.
