Question

2. The perimeter of a rectangular swimming pool is 154 m. Its length is 2 m more than
twice its breadth. What are the length and the breadth of the pool?
linear equations in one variable chapter 2 math book 8th class
​

Answer 1

Answer:length = 52 m

breadth = 25 m

Step-by-step explanation:

perimeter = 2(l+b)

l = 2b+2

perimeter = 2(2b + 2 + b)

perimeter = 2(3b + 2)

perimeter = 6b + 4

154m = 6b + 4

154m - 4m = 6b

150m = 6b

b = 150/6 m

b =25 m

l = 2b+2

l = 2*25 +2

l = 50 +2

l = 52 m

Answer 2

Step-by-step explanation:

______❤HEY! MATE❤______

LET THE BREADTH OF THE RECTANGULAR SWIMMING POOL BE

$x$

NOW, LENGTH IS 2 MORE THAN TWICE IT'S BREADTH

SO,

LENGTH WILL BE

$2x + 2$

GIVEN THAT :

PERIMETER OF RECTANGULAR SWIMMING POOL IS 154 M.

ACCORDING TO QUESTION :

$we \: know \: that$

$perimeter \: of \: reactangle = 2(length + breadth)$

$154m = 2(2x + 2 + x)$

$154 = 2(3x + 2)$

$154 = 6x + 4$

$150 = 6x$

$25m = x$

SO.

$breadth = 25m$

$lenght = 2x + 2$

$2 \times 25m + 2 \\ \\ \\ 50 + 2m \\ \\ 52m = length$
