Answer 2

Answer:

Total cost for carpenting the room = ₹720

Step-by-step explanation:

Given :

Side of the square room = 12m

Cost of carpeting per square meter = ₹5

To find :

Cost of carpenting in the room

Concept :

First we have to find the area of the square room . After that multiply the area with the cost of carpenting per square meter.

So , to find the area of the square room use this formula -:

$\boxed{\sf{A=S\:\times\:S}}$

Where,

A = Area of the square

S = Length of a side of the square

After that use this equation to find the cost of carpenting of the room -:

$\boxed{\sf{T=C\:\times\:A}}$

Where,

T = Total cost for the carpenting of the room

C = Cost of carpenting per square meter

A = Area of the square

Solution :

Area of the square -:

$:\implies\sf{A=12m\times12m}$

$:\implies\sf{A={144m}^{2}}$

Total cost for carpenting the room -:

$:\implies\sf{T=Rs.5\times{144m}^{2}}$

$:\implies\sf{T=Rs.720}$

So , the total cost of carpenting the room is ₹720 .
