Question

how much will it cost to make a gravel walk path of 3 metre wide all around a square Park whose area is 4884 1 metre square at rupees 2 per square metre​

Answer 1

Answer:

Area1 of a square is side x side

So, assuming side is X,  Area1 / X xX will give us length of aside.

Since the path is 3 m wide X + 3 will gives us the length of the outer square.

Now find the area2 using this lenght,

(x+3)(x+3)

Area2 - area1 = Area of gravel path or Area3

Area3  x Rs 2 sq m

Step-by-step explanation:

Answer 2

1.You've to find the side of square by finding the root of the area of square which is 488411 m2.

2.Then you've to subtract 3m two times from the side as the gravel walk is inside the park.

3.Then you've to find the area of new sqaure whose side you find out in step 2.

4.Then subtract the area of smaller square from the area of bigger square.

5.Then multiply the area which you got on step 4 with the given cost which is Rs 2/m2.

6.You will get your final answer after multiplying in step 5.
