Q. A verandah of width 2.25 m is constructed all along outside a room which is 5.5 m
long and 4 m wide. Find:
(1) the area of the verandah.
(ii) the cost of cementing the floor of the verandah at the rate of 200 per m²

Given:
Length of room =5.5m
Width of room =4m
Width of verandah which is constructed all along outside of room =2.25m
Cost of cementing of verandha = Rs 200 per sq.m
Length of room with verandah = 5.5+ 2.25+ 2.25 =10m
Width of room with verandah
=4+2.25+2.25=8.5m
Area of room=Length×Width
=5.5×4=22m²
Area of room with verandah= Length×Width
=10×8.5=85m ²
Area of verandah=
Area of room with verandah−Area of room
=85−22=63m²
Cost of cementing of verandah=Area×Rate
=63×Rs.200
=Rs.12600
