The school grounds are rectangular. It is surrounded by a fence, one side of which is 64 m, and the other is 19 m shorter. What is the area of the fenced area? The school building occupies a fifth of the school territory. And the orchard is one third of the remaining plot. What is the area of the orchard?

1) 64 – 19 = 45 (m) – the length of the other side of the fence, which fenced off the school territory.
2) 64 * 45 = 2880 (sq m) – the area of the entire fenced area of the school.
3) 2880/5 = 576 (square meters) – this is the area occupied by the school building.
4) 2880 – 576 = 2304 (square meters) – a plot of the school territory, excluding the area of the school building.
5) 2304/3 = 768 (sq m) – this area is occupied by an orchard.
Answer: the area of the fenced area is 2880 square meters; the orchard covers an area of 768 square meters.
