Which one is the formula for area of a triangle? * \( b \times L \) \( 2 L+2 w \) \( 1 / 2(b \times h) \)

The area of a triangle can be determined by using the formula \( \frac{1}{2}(b \times h) \), where \( b \) stands for the base of the triangle, and \( h \) is the height measured from that base to the opposite vertex. It’s a simple and effective way to calculate how much space the triangle occupies! In the real world, this formula comes in handy in various fields such as architecture and engineering. For example, when designing a roof or a triangular garden bed, knowing how to calculate the area can help you determine how much material you'll need or how much space you have to work with, making your projects go much smoother!
