Answer 2

The cost of polishing the floor of the room is Rs. 87.36

• A quadrilateral with equal angles and parallel opposite sides is referred to as a rectangle. Around us, there are a lot of rectangle items. The length and width of any rectangle form serve as its two distinguishing attributes. The width and length of a rectangle, respectively, are its longer and shorter sides.
• A rectangle is a closed, four-sided figure in two dimensions. All of a rectangle's angles are equal to 90 degrees, and its opposite sides are equal and parallel to one another.

Here, according to the given information, we are given that,

The length of the rectangular room floor = 140 cm. = 1.4 m.

The width of the rectangular room floor = 120 cm. = 1.2 m.

Then, the area of the rectangular room floor  = Length × Width = 1.4 × 1.2 = 1.68 m².

The price for 1 square meter is Rs. 52.

Then, the price of 1.68 m² is, Rs. (52 × 1.68) = Rs. 87.36

Hence, the cost of polishing the floor of the room is Rs. 87.36
