Question

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

Answer 1

Answer:

Area of room = 6×9.5=57m

Area of room including verandah = 12×8.5=102m

So area of verandah = 102−57=45m

So cost of cementing the floor of this verandah = 45×80=3600rupees

hope it helps..

Answer 2

Answer:

Area of room × 80

Step-by-step explanation:

area of room = 2lb× 2bh ×2hl

= 2 ×9.5×6× 2×6×1.25×2×1.25×9.5

= 40612.5sq.meter

Cost of cementing = 40612.5×80

= 3249000 Rs.
