Question

divide a rectangular card got from maths class into 16 units squared of length 1cm and breadth 1cm...what is the area of the rectangular card she got first ?.....write the length and breadth of any 3 rectangles formed by complaining 16 units squared together to get a single rectangle ? in such figures ,how many unit squares will be there on one side of square?

Answer 1

area of 1 card =1 cm sq
total area =16 × 1=16 cm square ...
So length of each square = root of 16
=4cm..

Answer 2

The area of the rectangle = $16.1^{2} = 16$ cm².

• Rectangle area in geometry refers to the area that a rectangle occupies on a two-dimensional plane. A quadrilateral, a form of two-dimensional object with four sides and four vertices, is what a rectangle is. The rectangle's four angles are all right angles or exactly 90 degrees. The rectangle's opposing sides are equal and parallel to one another. It should be noted that a parallelogram likewise has equal and parallel opposite sides, but the angles are not exactly 90 degrees.
• The dimensions of a rectangle determine its area. In essence, the area of a rectangle is equal to the sum of its length and breadth. In contrast, the circumference of a rectangle is equal to the product of its four sides. Consequently, we can say that the area of a rectangle equals the space enclosed by its perimeter. The area of a square will, however, be equal to the square of side-length in the case of a square because all of its sides are equal.

Here, according to the given information, a rectangular card got from maths class was divided into 16 units squared of length 1cm and breadth 1cm.

Then, the area of the rectangle = $16.1^{2} = 16$ cm².

Hence, the area of the rectangle = $16.1^{2} = 16$ cm².
