A room is 12 m wide and 4 m high. If the cost of colouring its walls at Rs 17 per sq. metre is Rs 3536, find the cost of plastering its floor and ceiling at Rs 25 per sq. metre.

Step-by-step explanation:

area of floor=l×b and area of ceiling also same

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
