Question

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

Answer 1

Answer:

Let the breadth of rectangular swimming pool be x metres. 

Then, its length =(2x+2) metres.

We know that the Perimeter of a rectangle =2(Length+Breadth)

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

According to the given condition, we have 

6x+4=154

⇒6x=154−4           ..[By transposing 4 to RHS]

⇒6x=150

⇒6x=6150         ...[Dividing both sides by 6]

⇒x=25 

Thus, breadth =25 m and length =25×2+2=52 m

Answer 2

Answer:

Let the breadth be x

then length is x+2

perimeter of rectangle=2(l+b)

154m=2(2+x+x)

154m=4+4x

4x=154-4

4x=150

x=150/4

x=37.50m

b=37.50

l=39.50m
