Question

The perimeter of rectangular swimming pool is 154 metre. It's length is 2 metre more than twice it's breadth. What are the length and the breadth of the pool

Answer 1

Given, perimeter =154 m
Let the breadth be x
Therefore length =2x+2
According to the question =2(l+b)
2(2x+2+x)=154
2(3x+2)=154
6x+4=154
6x=154-4=150
x=150/6=25m
Now, breadth =25m
Length =2x+2=25×2+2=52m...

Answer 2

Given Perimeter =154mLet the breadth =xlength =2x+2Perimeter of a rectangle => 2(l+b)2(l+b)=2(x+2x+2)=2(3x+2)=154=>3x+2=1542=>3x+2=773x=77−23x=75x=753=25Breadth =25length =25×2+2=50+2=55mAnswer : 25,52
