Question

The perimeter of a rectanglar swimming pool is 154m. Its lenght is 2m more than twice its breadth. what are the length and the breadth of the pool

Answer 1

Here is your answer. .
Rectangular swimming pool that means it is in rectangle shape.

According to the question

Let the breadth be. x
so the length will be.
l =2x+2
Perimeter (P) = 154m
We know that
P. = 2(l+b)
That is
154=2(2x+2+x)
4x+4+2x=154
6x=154-4
6x=150
x=150/6
x=25
That is breadth =b=x=25m
Length =2x+2
2×25+2
50+2
Length = 52m

Hope you understood. .....

Answer 2

The answer :

The length of pool = 2m more than twice of breadth

Breath of pool = x m
Length = ( 2x + 2m )

Perimeter = 2 × ( L + B )

154 = 2 × ( 2x + 2+x )

154 = 4x + 4 + 2x

154 = 6x + 4

154 - 4 = 6x

150 = 6x

150/6 = x

25m = x

Length = 2x + 2
Breadth = x

Putting the value of x

Length = 2 × 25 + 2 = 50 + 2 = 52m
Breadth = 25m
