Answer

To find the distance from the mirror to each end of the wall, we first need to calculate the space available on the wall after placing the mirror. The total width of the wall is 330 cm, and the width of the mirror is 100 cm. Thus, the space remaining on the wall is:

$330 ext{ cm} - 100 ext{ cm} = 230 ext{ cm}$

Step 2

Calculate the distance L

Answer

Since the mirror is placed in the middle of the wall, the available space (230 cm) is divided equally between the two ends. Therefore, the distance L can be calculated as:

$L = \frac{230 ext{ cm}}{2} = 115 ext{ cm}$
