Answer:

Length of the pool = 52 m

Width of the pool = 25 m

Step-by-step explanation:

Perimeter of rectangular pool = 154 m

Let the length of rectangular pool = l m

And width of the rectangular pool = w m

Formula, to calculate the perimeter of a rectangle is given by,

Perimeter = 2(Length + width)

By substituting values in the formula,

154 = 2(l + w) --------(1)

Since, "length of the pool is 2 m more than twice of its breadth"

l = 2 + 2w ---------(2)

Bu substituting value of 'l' from equation (2) to equation (1),

154 = 2[(2 + 2w) + w]

154 = 2(3w + 2)

77 = 3w + 2

3w = 75

w = 25 m

From equation (2),

l = 2 + 2(25)

l = 2 + 50

l = 52 m

Therefore, length of the rectangular pool is 52 m and width is 25 m.

−2x−(−5−4x)=−5(2x−7)
hoa [83]

Answer:

<em>x = 2.5</em>

Step-by-step explanation:

- 2x - ( - 5 - 4x ) =  - 5 ( 2x - 7 )

- 2x + 5 + 4x = - 10x + 35

- 2x + 5 + 4x = - 10x + 35

- 2x + 4x + 10x = 35 - 5

12x = 30

<em>x = </em>\frac{5}{2}<em> = 2.5</em>

Check the answer:

<em>L.H.S.</em> = - 2(2.5) - [ - 5 - 4(2.5) ] = <em>10</em>

<em>R.H.S.</em> = - 5 [ 2(2.5) - 7 ] = <em>10</em>
