Question

the perimeter of a rectangular swimming pool is 154 m. its length is 2m more than twice its breadth. what is the length and breadth.​

Answer 1

Answer:

$p = 154m \\ or \: 2(l + b) = 154 \\ or \: l + b = 77 \\ or \: 2b + 2 + b = 77 \\ or \: 3b = 77 - 2 \\ or \: 3b = 75 \\ or \: b = 25m \\ now \: l = 2b + 2 \\ = 2 \times 25 + 2 \\ = 52m$

Answer 2

Step-by-step explanation:

pls mark as brainliest

perimeter=154m

or 2(l+b)=154

or l+b=77

or 2b+2+b=77

or 3b=77−2

or 3b=75

or b=25m

now lenght=2b+2

=2×25+2

=52m
