Question

the floor of a rectangular hall a perimeter of 250 m. if its height is 6 m , find the cost of painting its four walls at the rate Rs 20 per m square

Answer 1

Rs. 10192 (not exactly sure)

Answer 2

⇒ Perimeter of rectangle= 2(l+b)
250 = 2(l+b)
l+b = 125m

⇒ Area of four walls = 4(l+b) h
4×125×6=3000m²

⇒ Cost of painting is given Rs 20/m²
So, cost of 3000m²=3000×20
= Rs 60,000
