Question

the perimeter of a rectangular park is 154m it's lenth is 2m more than twice its breadth what are the length and bredth

Answer 1

Answer:Let the breadth of rectangular park 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

⇒

6

x

​

=

6

150

​

...[Dividing both sides by 6]

⇒x=25

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

Answer 2

Answer:

let it's breadth be x and lenght be 2+2x

so,

perimeter=2(l+b)

154=2(2+2x+3x)

154=2(7x)

154=14x

x=14/154

=11

breadth =11

length=2+2*11

=4*11

=44
