Question

th perimeter of rectangular swimming pool is 154m. it's leangth is 2m more than its breadth . what are the leangth and breadth of pool?
​

Answer 1

Step-by-step explanation:

Let the breadth = x

Length of pool is 2m more than twice its breath

So length =(2x +2) m

The perimeter of swimming pool is 154m

2(l +b)=154

l + b = 154/2

(2x+2) + x = 77

3x = 77 – 2

3x = 75

x = 75/3

x=25.

So the breadth of pool is 25m

Length of pool is 2(25)+2=50+2=52m

Answer 2

SOLUTION

LET THE BREADTH BE X M

SO LENTH = 2+X

WE KNOW THAT PERIMETER OF RECTANGLE

= 2(L+B)

so ATQ,

2(2+x+x) = 154

= 4+2x+2x= 154

= 4x= 154-4

x = 150/4 = 37.5 m

breadth = 37.5 m

length = 2+x= 37.5 +2

= 39.5
