Answer:

A. 82 cm

Explanation:

You want the perimeter of the L-shaped figure that is 12.5 cm high and 28.5 cm wide.

Side lengths

The top two horizontal line segments have the same total length as the bottom horizontal line segment. We don't need to figure what the missing length is, because we only need their total for the perimeter.

The right side two vertical line segments have the same total length as the left vertical line segment. As with the horizontal segments, we don't need to figure out the missing length, because we only need their total for the perimeter.

Perimeter

The perimeter is the sum of horizontal line segments plus the sum of vertical line segments:

2(28.5 cm) + 2(12.5 cm) = 57 cm + 25 cm = 82 cm

The perimeter of the figure is 82 cm.
