Question

The walk along a tectangular swimming tank is 282 m. Its length is 3 m less than twice of its breadth what are the length and breadth

Answer 1

Answer:

perimeter=282m

length=2b-3,breadth=b

2(l+b)=282

2(2b-3+b)=282

2b-3+b=141

2b+b=138

3b=138

b=138/3

b= 46

substitute b value in length

2b-3=2(46)-3=89
