Here is ur answer :

Question 1 : Find the area of a square park whose perimeter is 44m.

Answer 1 :

Perimeter of square = 44

We have to find side of square.

Let the side be a

4 × side = 44

4a = 44


$a = \frac{44}{4}$


a = 11 m

Side = 11 m


✔️✴️Area of Park = side × side.

= 11 × 11

= 121 m²

Question 2 : The length and the breadth of a playground are 95m and 52m , respectively. find the cost of levelling the playground at the rate of 8 per sq.m rupees.

Answer 2 :

Length l of playground = 95 m

Breadth b of playground = 52 m

Area of playground = length × breadth

= l × b

= 95 × 52

= 4,940 m²

Cost for levelling the playground :

1 m² = Rs 8

4,940 m² = Rs 8 × 4,940

= Rs 39,520
