Question

1. Find the area of a square park whose perimeter is 80 m.

​

Answer 1

Answer:

Perimeter of Square = 4 × side

So, Side = perimeter/ 4

A/Q

Side = 80/ 4

= 20 m

Now

Area of the square = side × side = 20 × 20 = 400 m2

Answer 2

Answer :-

• The area of the square park is 400m².

Step-by-step explanation ::

To Find :-

• The area of square park

Solution ::

Given that,

• Perimeter of square park = 80m

First we need to find out the side of square, we can find out by applying the formula of perimeter of square,

As we know that,

Perimeter of square = 4 × side,

=> 4 × side = 80

=> side = 80/4

=> side = 20m

• The side of square is 20m.

According the question,

The area of square is,

As we know that,

Area of square = ( side )²,

=> Area = ( 20 )²

=> Area = ( 20 × 20 ) m²

=> Area = 400m²

• The area of the square park is 400m².

Formulas used :-

• Perimeter of square = 4 × side
• Area of square = ( side )²
