four walls at the rate of a 10 per m² is 20000. Find the height of the wall.
​

Answer 1

Answer:

10m

Step-by-step explanation:

Perimeter of a square shaped floor=200 m 4a-200 a=50m Thus, length (a) =50 m, breadth (a) =50 m and Let height =h Area of wall painted for Rs 10=1 m2 Area of wall painted for Rs 20000-2000 m Thus area of four walls =2000 m 2(length + breadth) height=2000 2(50+50) h=2000b h=10 mn Thus height of the wall is 10 m.
