Answer:
33m 40cm.
Explanation:
One side of the shed measures 8 meters and 35 centimetres, which is 800 + 35 = 835 centimetres.
Since the shed is a square, all side lengths are 835 centimetres long. So, the perimeter is 835 * 4 = 3,340 centimetres. That means that the perimeter is 33 meters and 40 centimetres.
Hope this helps!
