Answer 1

Answer:

p=154m

p=2l+2b

154=2l+2b

l+b=77 ------(1)

2b+2=l

2b-l=-2 -----(2)

l+b=77

2b-l=-2

3b=75

b=25m

l=2b+2

l=2×25+2

l=50+2

l=52m

hence length is 52 m

Answer 2

Answer:

Let the length of the swimming pool be x

L=2m more than twice the breadth.

l=2m+2x

p=154

2*(l+b)=154=2*(2m+2x+x)=154m=25m

L=2+2xm=2+2*25=52

B=xm=25....
