Hint: Assume the breadth of the pool is x m. The length is 2 m more than twice its breadth. So, the length of the pool is (2x+2). The perimeter of the pool is 154 m. Now, put the values of the length, breadth and perimeter in the formula, Perimeter=2(length+breadth)

. Now, get the value of x. The measure of breadth is x. Put the value of x in the equation (2x+2) and get the value of length. Now, we have the values of the length and the breadth.

Complete step by step solution:

According to the question, it is given that the perimeter of a rectangular swimming pool is 154 m. Its length is 2 m more than twice its breadth.

The perimeter of the rectangular swimming pool = 154 m ……………………………(1)

Let us assume the breadth of the perimeter be x.

The breadth of the rectangular swimming pool = x ………………………(2)

Since the length of the rectangular pool is 2 more than twice its breadth so, we get length as,

The length of the rectangular pool = 2x+2 ………………………(3)

Since the swimming pool is in the shape of a rectangle, here we can apply the formula of the perimeter of the rectangle.

We know the formula of the perimeter of the rectangle, Perimeter=2(length+breadth)

……………………………(4)

Now, putting the values of the breadth from equation (2) and length from equation (3), in equation (4), we get

⇒Perimeter=2(2x+2+x)

⇒Perimeter=2(3x+2)

……………………………..(5)

From equation (1), we have the value of the perimeter.

Answer:

kg = 1000g

so , 2 = 2/1000

= 0.002 kg
