Question

The perimeter of a rectangular swimming pool is 154 its length is 2 metre more than twice its breadth what are the length and the breadth of the fool​

Answer 1

Answer:

perimeter of rectangle is 2(l+b)

then let the breadth be X

so,2(2X+2+X)=154

2(3X+2)=154

6X+4=154

6X=154-4

6X=150

X=150/6

X=25

so breadth is 25

then length is 2X+2=2x25+2=52

Answer 2

Step-by-step explanation:

Let Breadth = x

Length = 2+2x

Now perimeter of rectangle = 2(l+b)

2(l+b)= 154

2(2+2x+x)=154

2(2+3x)=154

2+3x = 77

3x=75

x=25 m

Required Breadth =25

Length = 2+2x 25 =52 m

Hope it helps you
