Answer 1

Answer:

$\sf{\rightarrow {A= l \times b}}$ $\sf{\rightarrow {A= l \times b}}$ $\sf{\rightarrow { 12 \times b= 96 m²}}$

Length of Rectangular room ( l ) -: 12 m

Breadth of Rectangular Room ( b ) -: ??

Are of Rectangular room ( A ) -: 96 m² .... [ From 1 ]

The total cost in which room is floored is Rs. 2592 .

The rate of flooring is Rs. 27 m².$\sf{\frac{The\: total \:cost\:in\:which\:room\:is\:floored.}{The\:rate\:of\:flooring\:at\:per\:m²}}$Area of parallelogram is 12 cm² $\sf{\rightarrow {A= l \times b}}$Perimeter of Rectangular room is 40 m . The total cost in which room is floored is Rs. 2592 .

The rate of flooring is Rs. 27 m². The total cost in which room is floored is Rs. 2592 .

Explanation:

All changes in the world are one of the two types – Reversible changes and irreversible changes. A change which can happen backward, that is, can be reversed is called a reversible change. If you keep water in the freezer for some time, it transforms into ice. But as soon as you take it out of the freezer, it turns into water again. This is a reversible change. Similarly, if you boil water, it evaporates and becomes water vapor. When you cool this vapor down, it turns back to water.
