1.	1 A verandah of width 2.25m is constructed all along outside a room which is 5m long and 3m wide. Find1.the area of verandah and2.the cost of cementing the floor of verandah at the rate of rupees 275 per m2
Answer» Area of room Ar = lengthbreadth= 53 = 15 m^2 Area of outer of verandah Ao= lengthbreadth= (5+4.5)(3+4.5)= 9.57.5 = 71.25 1)Area of verandah = Ao - Ar = 71.25 - 15 = 56.25 m^2 2)cost of cementing floor= 56.25275 = Rs 15468.75

1 A verandah of width 2.25m is constructed all along outside a room which is 5m long and 3m wide. Find1.the area of verandah and2.the cost of cementing the floor of verandah at the rate of rupees 275 per m2

Answer»

Area of room Ar = length*breadth= 5*3 = 15 m^2

Area of outer of verandah Ao= length*breadth= (5+4.5)*(3+4.5)= 9.5*7.5 = 71.25

1)Area of verandah = Ao - Ar = 71.25 - 15 = 56.25 m^2

2)cost of cementing floor= 56.25*275 = Rs 15468.75
