Question

The perimeter of a rectangular swimming pool is 154m.if the length is 2m and twice the breadth find the length and breadth

Answer 1

Answer:

Step-by-step explanation:p= 2(l+b)

=154=2(2+b)

154/2=2+b

77=2+b

77-2=b

75=b

Answer 2

Answer:

perimeter of a rectangle swimming pool = 154 m

length of the pool =2 B +2

perimeter =2(L+B ) =154

2(2 B+2+B) =154

4 B+4+2 B =154

6 B +4 =154

6 B =154–4 =150

B =150/5 =25 m

L =2*25+2 =52 m

length of the pool =52 m

breadth of the pool =25 m
