Question

the perimeter of a rectangular swimming pool is 154m.Its lenght is 2m more than twice its breadth.What are the lenght and breadth of the pool??
need. step by step answer​

Answer 1

Step-by-step explanation:

Let breadth of rectangle swimming pool = x

Given,

Length is 2m more twice its Breadth

Length = (2x+2)m

Now,

Perimeter = 2 (Length+Breadth)

= 2 (2x+2+x)

= 2 (3x+2) = 6x+4

Given,

Perimeter = 154m

6x+4 = 154

6x = 154-4

6x = 150

x = 150/6

x = 25

Breadth = x = 25 m

Length = 2x+2 = 2×25+2 = 150+2 = 52m

HOPE THIS HELPED YOU ✌

Answer 2

Answer:

Length = 52m

Breadth = 25 m
