knows that a = (1/2) b. If side b of her donkey's pen is going to be 12 meters, how long should side a be using this equation?

Answer 1

Given the equation \( a = \frac{1}{2} b \) and the value of side \( b \) is 12 meters, we can substitute the value of \( b \) into the equation to find \( a \).

\[ a = \frac{1}{2} \times 12 \]

Calculating that, we get:

\[ a = 6 \text{ meters} \]

Therefore, side \( a \) should be 6 meters long.
