Question

The perimeter of a rectangular swimming pool is 308 m. It's length is 4 m more than twice its breadth. What is the length of the swimming pool?​

Answer 1

Answer:

length=104m

Step-by-step explanation:

Given,

2(l+b)=308

l+b=154

2x+4+x=154

3x=150

x=50

so,length=2*50+4=104

Answer 2

Answer:

let,

breadth=x then,

length=2x+4

perimeter=308

2(length+breadth)=308

2(2x+4+x)=308

2(3x+4)=308

6x+8=308

6x=308-8

6x=300

x=300/6

x=50

therefore breadth of the swimming pool =50m

length of the swimming pool =2x+4

=2×50+4

=100+4

=104m
