Description: We already know that the square and rectangle are closed shapes with four sides. Let's watch this video to study how to calculate the area of a given square...

Question

Match the following:

$(a)$	Area of a rectangle	$(i)$	$π r^{2}$
$(b)$	Area of a square	$(ii)$	$4 \times$ side
$(c)$	Perimeter of a rectangle	$(iii)$	$l \times b$
$(d)$	Perimeter of a square	$(iv)$	(side)^$2$
$(e)$	Area of a circle	$(v)$	$2 (l + b)$

Accepted Answer

$(a)$ Area of a rectangle.

We know that the region covered by the rectangle in two-dimensional plane is the area of the rectangle.

As a rectangle has two pairs of equal and parallel line.

The area is the product of the length and breadth.

$(i)$ Area of rectangle $= (l \times b) sq . units$ .

Hence, option $(iii)$ matches.

$(b)$ Area of a square.

We know that the region covered by the square in two-dimensional plane is the area of the square.

As a square has all side equal in measurement.

The area is the square of its sides.

$∴$ Area of square $= (side)^{2} sq . units$ .

Hence, option $(iv)$ matches.

$(c)$ Perimeter of a rectangle.

We know that the perimeter is the total distance cover by the rectangle in two -dimensional around its outside.

As a rectangle has two pairs of equal and parallel line.

The perimeter is twice the product of the sum of its length and breadth.

$∴$ Perimeter of a rectangle $= 2 (l + b) units$ .

Hence, option $(v)$ matches.

$(d)$ Perimeter of a square.

We know that the perimeter is the total distance cover by the square in two -dimensional around its outside.

As a square has all side equal in measurement.

The perimeter is the sum of all sides.

$∴$ Perimeter of a square $= (4 \times side) units$ .

Hence, option $(ii)$ matches.

$(e)$ Area of a circle.

We know that the region covered by the circle in two-dimensional plane is the area of the circle.

As circle has no straight line we can use the other dimensions such as diameter and radius to calculate the region covered.

$∴$ Area of a circle $= (π r^{2}) sq . uints$ .

Hence, option $(i)$ matches.

Below is the complete table with all the matches.

Area of a rectangle $(d)$ $l \times b$

Area of a square (side)^$2$

Perimeter of a rectangle $(e)$

Perimeter of a square $4 \times$ side

Area of a circle $π r^{2}$

Match the following:

$(a)$ Area of a rectangle $(i)$ $π r^{2}$

$(b)$ Area of a square $(ii)$ $4 \times$ side

$(c)$ Perimeter of a rectangle $(iii)$ $l \times b$

$(d)$ Perimeter of a square $(iv)$ (side)^$2$

$(e)$ Area of a circle $(v)$ $2 (l + b)$
