Question

find the area of a square park whose perimeter is 320 metre​

Answer 1

SOLUTION :-

ANSWER :

The area of a square park is 6400 metre.

GIVEN :

The perimeter of a square park is 320 metre.

TO FIND :

Area of a square park = ?

EXPLANATION :-

FORMULA USED HERE :

• Perimeter = 4 × side
• Area = side × side

PUTTING THE VALUES ACCORDING TO THE GIVEN FORMULAS :

Perimeter of a square park = 320 metre. [Given]

= 4 × side

= 320/4

= 80 metre

Area of a square park = side × side

= 80 metre × 80 metre

= 6400 metre

Answer 2

S O L U T I O N :

• Perimeter of the square park = 320 m

Let side be a .

As we know that in a square,

• $\boxed{\bf{Perimeter =4a}}$

Substitute the values :-

${:}\leadsto\sf 4a=320$

${:}\leadsto\sf a=\cancel{\dfrac {320}{4}}$

${:}\leadsto \underline {\tt side=80\:m}$

Now ,

• $\boxed {\bf{Area=(a)^2 }}$

Substitute the values :-

${:}\leadsto\sf Area=(80)^2$

${:}\leadsto{\underline {\boxed {\bf \pink{{Area=6400\:m^2}}}}}$
