Area of parallelogram: \( A=b h \), for \( b \)

To isolate \( b \) in the formula \( A = b h \), you simply rearrange the equation by dividing both sides by \( h \). This leads you to the formula \( b = \frac{A}{h} \). This means to find the length of the base \( b \), you take the area \( A \) of the parallelogram and divide it by its height \( h \). Voilà, you’ve got your base! Now, think about real-world situations where you might need this knowledge. For instance, if you're planning to lay down a new patio in the shape of a parallelogram, knowing how to calculate the area and find the base length can help ensure you purchase the right amount of materials. So next time you're measuring a space, remember: the area can help you figure out everything from flooring to gardening layouts!
