Question

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 ​

Answer 1

Answer:

Step-by-step explanation:

perimeter of rectangle = 2(l x b)

let the breadth be x

and length be ( 2+2x )

equation:

2(x+2x+2) = 154

on opening the bracket

2x + 4x + 4 = 154

6x + 4 = 154

6x= 154 - 4

6x = 150

x = 150/6

x = 25

therefore,

breadth = x = 25 m

length = 2x + 2 = 2(25) + 2

                        = 50 + 2

                        = 52 m

Answer 2

Answer:

breadth=25 m , Length=52 m

Step-by-step explanation:

$L=2+2b\\\\154=2(2+2b+b)\\154/2=2+3b\\77=2+3b\\77-2=3b\\75=3b\\75/3=b\\25=b$$154=2(l+25)\\154/2=l+25\\77=l+25\\77-25=l\\52 m = l$
