a verandah of width 2.25m is constructed all along outside a room which is 5.5m long and 4m wide. find i) the area of verandah ii) the cost of cementing the floor of the verandah at the rate of rs 200 per m square

  • 5

Area of verandah = Area ofouterfigure - Area of inner figure

Area of outer figure = (5.5 + 2.25 + 2.25) x (4 + 2.25 + 2.25)

= 10 x 8.5

= 85 m2

Area of inner figure = 5.5 x 4

= 22 m2

Area of verandah = 85 - 22

= 63 m2

Cost = 63 x 200

=. 12,600
