Question

The length of a rectangular park is 2times the breadth of the park the perimeter of the park is 180 cm. Find the length and the breadth of the park.​

Answer 1

Here the relation between length and breadth of a rectangular park is given

length= 2(breadth)

Also, the perimeter of the park is given to be 180 cm

We have to find the length and breadth of the park

We will use the formula of perimeter of rectangle

perimeter = 2 ( length + breadth )

180 = 2 { 2(breadth) + breadth}

90 = 3breadth

breadth = 30

So, length = 2(30)

= 60

Hence, the length and breadth of the rectangle will be 60 cm and 30 cm respectively

Answer 2

Step-by-step explanationlet breadth of rectangular park=a

length of rectangular park=2a

perimeter of rectangular park=2(length+breadth)

=2(2a+a)=180cm

6a=180

a=30

breadth of rectangular park is 30 cm length of rectangular park is 60 cm.
