Black building
Jozef built a building with a rectangular footprint of 3.9 m × 6.7 m. Calculate by what percentage the building exceeds the legal limit of 25 m² for a small building. A building constructed without planning permission is called an illegal building. Also calculate the angle between the walls that would keep the footprint within the 25 m² limit, given the same wall lengths, if the building were built with a non-rectangular shape.
