Question

A verandah of width 4.75m is constructed all along outside of a room which is 20.5m along and 15.5m wide find:(a) the area of verandah.(b) the cost of putting the tiles in the verandah the rate of rs20 per m2

Answer 1

Area of the room(inner rectangle)=l×b

=20.5×15.5

=317.75 square m

Dimensions of outer rectangle=

l=20.5+4.75=25.25m

b=15.5+4.75=20.25m

Area of outer rectangle=l×b

=25.25×20.25

=511.3125 square m

Area of verandah=Area of outer rectangle-Area of inner rectangle

=511.3125-317.75

=193.5625 square m

Cost of arranging tiles in varendah=193.5625×Rs.20=Rs.3871.25
