Question

please give me the solution of the question no. 8​

Answer 1

Step-by-step explanation:

Given -

• Perimeter of a rectangular swimming pool is 154 m.
• Its length is 2 m more than twice its breadth.

To Find -

• Length and breadth of the pool

Let the breadth of the rectanglular pool is x m

Then,

Length is (2x + 2) m

Now,

As Given -

• Perimeter of rectangular pool = 154 m

» 2(l + b) = 154

» l + b = 77

» (2x + 2) + x = 77

» 3x + 2 = 77

» 3x = 77 - 2

» 3x = 75

» x = 75/3

• » x = 25 m

Hence,

The breadth of the rectanglular pool is 25 m

And

The length of the rectanglular pool is

(2x + 2)

» 2(25) + 2

» 50 + 2

• » 52 m

Verification -

Perimeter = 2(l + b)

» 154 = 2(52 + 25)

» 154 = 2(77)

» 154 = 154

LHS = RHS

Hence,

Verified..

Answer 2

$\huge \mathfrak{Answer:-}$

$\implies$ Length 52m.

$\implies$ Breadth = 25m

$\large\underline\mathrm{Given:-}$

• perimeter of a rectangular swimming pool is 154.
• it's length is 2m more than twice it's breadth.

$\large\underline\mathrm{To \: find}$

• Length and Breadth of the pool.

$\large\underline\mathrm{Solution}$

• Let the breadth of the rectangular pool is x m.

$\large\underline\mathrm{then,}$

$\large\underline\mathrm{Length \: is \: (2x \: + \: 2)m}$

$\large\underline\mathrm{perimeter \: of \: the \: rectangular \: pool \: = \: 154m.}$

$\implies$ (2x + 2) = 154

$\implies$ l + b = 77

$\implies$ (2x + 2) + x = 77

$\implies$ 3x + 2 = 77

$\implies$ 3x = 77 - 2

$\implies$ 3x = 75

$\implies$ x = 25

$\large\underline\mathrm{hence,}$

$\large\underline\mathrm{the \: breadth \: of \: the \: rectangular \: pool \: is \: 25m.}$

$\large\underline\mathrm{and,}$

$\large\underline\mathrm{the \: length \: of \: the \: rectangular \: pool \: is \: (2x \: +\: 2)}$

$\implies$ 2(25) + 2

$\implies$ 50 + 2

$\implies$ 52m.
