Question

A park is in the shape of circle and a field is in the shape of a rectangle. Which shape

has greater perimeter and area if the radius of the circular park is 7m and dimension of the

rectangular field is 6m x 5m.​

Answer 1

Answer:

Step-by-step explanation:

ANSWER:-

First Calculating of Circle:-

We know that Circumference or Perimeter of Circle is

$\boxed{2 \pi r}$

So, we are already given as Radius 7 metre.

Jotting it down,

$\sf{2 \times \pi \times 7}$ = $\sf{14 \times 3.14 = 43.96\ metres$ (approx. value)

The area of a circle is

$\boxed{\pi \times r^2}$

$= 3.14 \times 49 = 153.86$ metre square.

Now Calculating of Rectangular Field:-

We know that

P = 2(L+B)

• P is Perimeter
• L is Length
• B is height

So, we are also given Length as 6 metre and Breadth as 5 metre.

Placing them directly:-

$\boxed{P = 2(6+5)} = \sf{22\ Metres}$

Area is Length * Breadth

= $6 \times 5 = 30\ m^2$

As Circle has greater Perimeter and Area, Circle is the Answer.

Answer 2

$\huge \purple A \purple N \purple s \purple W \purple e \purple \R : -$

Circumference of Circle = 2πr

=> 2 × 3.14 × 7 = 43.96 m

Area of circle = πr^2

=> 3.14 × 49

=> 153.86 m^2

Perimeter of Rectangle = 2 ( l + b )

=> 2 ( 6 + 5 )

=> 12 + 10

=> 22 m

Area of Rectangle = l × b

=> 6 × 5

=> 30 m^2

Circle has greater perimeter and area .

Circle has greater perimeter and area . Hence , circle is your answer .
