Answer 1

Answer:

A room 9.5m long and 6m wide is surrounded by a 1.25-m-wide verandah. Calculate the cost of cementing the floor of this verandah at rupees 80 per square ?

According to the question we know that A room is 9.8m long and 6m wide and it's surrounded by a 1.25m wide verandah.

Now,

Area of room = 6 × 9.5 = 57m

Now,

The length of verandah

=> 9.5 + 1.25 × 2 = 12m

Breadth of verandah = 6+1.25 × 2 = 8.5m

Then,

The area of verandah = 12 × 8.5 = 102m²

Total area of room = 102 - 57 = 45

Now,

Cost of cementing 80 × 45 = 3600
