Answer 1

Answer:

Q. 1=

Given:

Perimeter=150m

⇒Area of 4 walls =2lh+2bh

=2(b+l)h

⇒Perimeter of floor of wall =2l+2b

⇒2(l+b)=150 m

∴ Area of 4 walls =2(l+b)h

=150h m

⇒Cost of painting per m

area = Rs. 10

⇒Cost of painting 150h m

area = Rs(150h×10)

= Rs.1500h

⇒Painting cost of walls = Rs. 9000

⇒1500h=9000

15=90

⇒h= 6m
