Question

Find the area of a square park whose perimeter is 320m.
​

Answer 1

Step-by-step explanation:

Given:

perimeter = 320m

find:

let the side be x

perimeter of square = 4× side

320 = 4x

320/4=x

80 = x

side = 80m

According to question

Area of square = side × side

= 80 ×80

= 6400m^2

Therefore the area of square is 6400m^2.

Answer 2

Answer:

Question

Find the area of a square park whose perimeter is 320m.

Solution

we know that perimetre of square is given by

${ \underline{ \boxed {\color{grey}{perimetre = 4side}}}}$

Let us assume the unknown side of square be X.

$\to \: 320 = 4 \times x \\ \\ \to \: x = \frac{320}{4} \\ \\ \to \: x = 80 \: m$

The side of the square is 80 metre.

We know that area of square is -:

${ \underline{ \boxed{ \color{grey}{area = {side}^{2} }}}}$

$\to \: area \: = {80}^{2} \\ \\ \to \: area \: = 6400 {m}^{2}$

The area of the given square is 6400 m²
