A) \( A=b \times a \) B) \( A L \times h=a \times h \) C) \( A=L \times a \) D) \( A=b \times h \)

Let's dive into the world of area formulas! In geometry, the area (\( A \)) of various shapes can often be calculated using simple formulas. For example, with rectangles and parallelograms, we utilize \( A = b \times h \), where \( b \) is the base and \( h \) is the height. This formula makes it easy to visualize how the two dimensions multiply together to fill the space! Additionally, don’t forget about common mistakes! Students often confuse the base and height in shapes like triangles and parallelograms. Remember, the height must be perpendicular to the base! Drawing the shape can help you visualize the correct base-height pairing, which will lead to accurate calculations and a better understanding of geometry in real life.
