Solving the formula $A = rac{1}{2} b h$ for $b$

To solve the triangle area formula $A = rac{1}{2} b h$ for the base $b$ , follow these steps:

Write the formula: $A = rac{1}{2} b h$ .
Clear the fraction by multiplying both sides by $2$ : $2A = b h$ .
Isolate $b$ by dividing both sides by $h$ : $b = rac{2A}{h}$ . This process rewrites the formula to directly calculate the base when the area and height are known.
