Question

A room 9.5m long and 6m wide is surrounded by a 1.25m wide verandah. calculate the cost of cementing the floor of this verandah at Rs 80 per m2

Answer 1

The required amount is rs 1675.

Answer 2

Answer:

Rs.1675

Step-by-step explanation:

Length of room = 9.5 m

Breadth of room = 6 m

Since we are given that A room is surrounded by a 1.25 m wide verandah.

So, Length of room with verandah  = 9.5 m +1.25 m= 10.75 m

Breadth of room with verandah  = 6 m +1.25 m= 7.25 m

Area of verandah = Outer area - inner area

                             =$(10.75 \times 7.25) - (9.5 \times 6)$

                             =$20.9375 m^2$

Cost of cementing 1 sq. m. = Rs.80

Cost of cementing 20.9375 sq.m. = 80*20.9375= Rs.1675

Hence the cost of cementing the floor of verandah is Rs.1675
