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 breadth of the pool​

Answer 1

Answer:

given :

perimeter =154m

l=2+2b---(1)

to find ; l&b

perimeter of a rectangle =2(l+b)

154=2(l+b)

154=2[(2+2b)+b] from eq (1)

154=2[2+3b]

154=4+6b

154-4=6b

150=6b

150/6=b

25=b---(2)

Now,from eqn (1) and (2)

l=2+2b

l=2+2×25

l=2+50

therfore,l=52m & b=25m
