## What is a Rectangle?

A rectangle is classified as a quadrilateral, a two-dimensional shape with four sides.It’s important to differentiate between a rectangle and a square.

While a square represents a specific type of rectangle where all sides are of equal length, a rectangle can have varying length and width measurements as long as it maintains the properties of right angles and parallel sides.Two defining characteristics distinguish a rectangle:

1. All four internal angles of the rectangle measure exactly 90 degrees (π/2 radians). This translates to each corner forming a perfect square where the sides meet.
2. The opposing sides of the rectangle are both parallel and congruent (identical in length). This property bestows upon the shape a sense of balanced proportions.

## Area of Rectangle Formula

In simpler terms, the area of a rectangle is like the amount of flat space the rectangle fills. We find this area by multiplying the rectangle’s length by its width. Think of it like covering the rectangle with tiny squares: the more squares you can fit in a row (length) and the more rows you can fit (width), the greater the total area.

The symbol for area is typically capitalized “A,” and the length and width are represented by “l” and “b” (or sometimes “w”). So the formula we use to find the area looks like this: A = l × b. The answer will always be in square units, because we are essentially counting the number of tiny squares that fit within the rectangle.

## Area of Rectangle : Sample Solved Questions

Q. A rectangular carpet has an area of 20 sq m. If the length is twice the breadth, what is the breadth?

a) 1 m

b) 2 m

c) 3 m

d) 4 m

Answer: b) 2 m (Let breadth = x. Then length = 2x. Area = 2x * x = 20. x^2 = 10. x = sqrt(10). Since width cannot be negative, x = 2)

Q. The diagonal of a rectangle divides it into two congruent right triangles. If the area of one triangle is 12 sq cm, what is the area of the rectangle?

a) 12 sq cm

b) 24 sq cm

c) 36 sq cm

d) 48 sq cm

Answer: c) 36 sq cm (Area of rectangle = 2 * Area of triangle = 2 * 12 = 24 sq cm)

Q. Tiles with a width of 10 cm are used to cover a rectangular floor. If 30 tiles are used in a row, what is the minimum possible length of the floor (in cm)?

a) 100

b) 200

c) 300

d) 400

Answer: b) 200 (Width of floor = Width of tile * Number of tiles = 10 * 30 = 300 cm. Since length cannot be smaller than width, minimum length = width = 300 cm)

Q. A rectangular park has a perimeter of 40 meters. If the length is 3 meters more than the breadth, what is the area of the park (in sq m)?

a) 54 sq m

b) 63 sq m

c) 72 sq m

d) 81 sq m

Answer: c) 72 sq m (Let breadth = x. Then length = x + 3. Perimeter = 2(x + x + 3) = 40. 4x = 34. x = 8.5. Area = (x + 3)x = (8.5 + 3)(8.5) = 72.25 ≈ 72 sq m)

Q. A rectangular sheet of paper is folded in half along its length. The resulting area is 18 sq cm. What is the original area of the paper?

a) 18 sq cm

b) 36 sq cm

c) 54 sq cm

d) 72 sq cm

Answer: b) 36 sq cm (The folded area represents half of the original sheet. Original area = Area of folded sheet * 2 = 18 * 2 = 36 sq cm)

Q. A rectangular garden is divided into two square plots. The total area of the garden is 48 sq m, and the area of one square plot is 16 sq m. What is the area of the other square plot (in sq m)?

a) 16 sq m

b) 24 sq m

c) 32 sq m

d) 48 sq m

Answer: a) 16 sq m (The garden consists of two identical squares. If one square plot has an area of 16 sq m, the other one must also have the same area)
