Question

A man spent rs.368640 to build a square room for 40 person to sit.find the perimeter of the room assuming each person gets equal space to sit in the room​

Answer 1

Answer:

384 unit

Step-by-step explanation:

Since it is given that Rs 368640 is spent by a man for a square room.

We have to arrange a seat for 40 person.

Area of the square = $\frac{368640}{40}$ = 9216 sq.unit

         We know that the area of the square is a² where a is the side of the square.

a²=9216 sq.unit

a=$\sqrt{9216}$=96 unit

Hence,

             Perimeter of the square is 4a.

  Therefore,

             4a= 4× 96 =384 unit

Answer 2

Answer:

The perimeter of the room assuming each person gets equal space to sit in is 384 unit.

Given Data:

Amount Spent = Rs.368640

Number of person = 40.

To Find:

Perimeter of the room?

Step 1:

Since it is given that Rs 368640 is spent by a man for a square room.

We have to arrange a seat for 40 person.

Step 2:

Area of the square = \frac{368640}{40}  = 9216 sq.unit

Step 3:

We know that the area of the square is a^{2} where a is the side of the square.

$a^{2} =9216$ sq.unit

a= $\sqrt{9216}$ =96 unit

Step 4:

Hence, Perimeter of the square is 4a.

Therefore, 4a= 4 $\times$ 96=384 unit.
