The cost of flooring a room is ₹2592. The rate of flooring is ₹27 per square meter. If the room is 12 m long, what is the perimeter of the room?

${\huge {\bf {\underbrace {Answer}}}}$

Given:-

• The cost of flooring a room is ₹ 2592.
• The rate of flooring is ₹ 27 per square meter.
• The room is 12 m long.

To Find:-

• The perimeter of the room,

Solution:-

• We have to find the area of the room,

${\sf {\implies {Area\: of\: floor = {\large \frac{2592}{27}}}}}$

${\sf {\implies {Area\: of\: room\: floor = 96\: {m}^{2}}}}$

${\pink {\sf {\boxed {Area\: of\: room\: floor = Length × breadth}}}}$

• Area of room floor = 96

${\sf {\implies {96 = 12 \times b}}}$

${\sf {\implies {b = {\large \frac{96}{12}}}}}$

${\green {\boxed {\sf {\implies {Breadth = 8\: meter}}}}}$

• The breadth of the room is 8 meter.

Now,

${\pink {\boxed {Perimeter\: of\: the\: room= = 2 (l + b)}}}$

${\sf {Perimeter\: of\: the\: room = 2 (12 + 8)}}$

${\sf {Perimeter\: of\: the\: room = 2 × 20}}$

${\green {\boxed {\sf {Perimeter\: of\: the\: room = 40\: meter}}}}$

Perimeter of the room is 40 meter.
