Answer 2

Answer:

The cost is Rs 86100

Step-by-step explanation:

$\text{Given that a hall is 16 m long and 12 m broad.}$

$\text{we have to find the cost of carpenting it at rs }615 per m^2$

$\text{ after leaving a margin of 1 meter all around.}$

Length = 16 m

Breadth =12 m

Now carpenting is done after leaving a margin of 1 meter all around

∴ Required length = 16 - 1 - 1=14 m

Breadth = 12 - 1 - 1=10 m

$Area=Length\times breadth=14\times 10=140 m^2$

$\text{The cost of carpenting for 1 }m^2=Rs 615$

$\text{The cost of carpenting for 140 }m^2=Rs (615\times 140)=Rs 86100$

Hence the cost is Rs 86100
