Question

The length and breadth of a rectangular park are 100m and 60m respectively. There is

a square swimming pool of side 8m inside the park. What will be the cost of putting

grass in the remaining part of the park at the rate ₹ 25 per square meter?​

Answer 1

Answer:

Rs.1,48,400

Step-by-step explanation:

length of the park= 100m

breadth of the park= 60m

Area of rectangular park= l×b

=100×60

=6000 sq m

side of swimming pool= 8m

Area of square swimming pool= side ×side

=8×8 =64sq m

Area left for putting grass= area of park - area of

swimming pool

= 6000-64

=5936sq m

cost of putting grass on 1 sq m= Rs. 25

cost of putting grass on 5936sq m= Rs.25×5936

= Rs. 148400

Answer 2

Answer:

$\bigstar{\bold{Total\:cost=Rs.148400}}$

Step-by-step explanation:

$\Large{\sf{\underline{Given:}}}$

• Length of the rectangular park = 100 m
• Breadth of rectangular park = 60 m
• Side of square pool = 8 m

$\Large{\underline{\sf{To\:Find:}}}$

• Cost of putting grass on the remaining part of the park at the rate Rs 25 per square meter.

$\Large{\underline{\sf{Solution:}}}$

➛ First find the area of the rectangular park.

➛ Area of a rectangle is given by,

   Area of a rectangle = l × b

➛ Substitute the values,

   Area of the rectangular park = 100 × 60

   Area of the park = 6000 m²

➛ Hence area of the park is 6000 m².

➛ Now we have to find the area of the swimming pool in the form of a square.

➛ Area of a square is given by,

   Area of a square = side × side

➛ Substitute the data,

   Area of the swimming pool = 8 × 8

   Area of the swimming pool = 64 m²

➛ Hence area of the swimming pool is 64 m².

➛ Now the remaining area is given by,

   Remaining area = Area of park - Area of swimming pool

   Remaining area = 6000 - 64

   Remaining area = 5936 m²

➛ Hence the remaining area is 5936 m²

➛ Now the total cost of grassing the park is given by,

   Total cost = Area to be covered by grass × Cost per m²

    Total cost = 5936 × 25

   Total cost = 148400 rupees

➛ Hence total cost of covering the remaining area by grass = Rs. 148400

    $\boxed{\bold{Total\:cost=Rs.148400}}$
