Answer 1

Step-by-step explanation:

A room is. 7 m long and 5 m broad . It has one door measuring 2m by 1.5 m and two windows, each measuring 1.5 m by 1m. The cost of painting the walls at ₹12.50 per sq m is ₹825.find the height of the room

Answer:

Area to be paint = LSA of rect room -(ar of door +2*ar of window)

=2(L+B)H- (2*1.5+2*1.5*1)

=2(7+5)H -(3+3)

=24H- 6 sqm

area to be paint = total cost/cost per sqm

24H-6. =. 825/12.5

24H-6. = 66

24H. =66+6

H =72/24

H. =3m
