Question

The length of a rectangular park is
thrice its breadth. If the perimeter
of the park is 168 metres, find its
dimension.​

Answer 1

Answer:

63 m; 21 m

Step-by-step explanation:

Let , the breadth be 'x'.

Length of the rectangular park=3x

Given that, perimeter=168 m

2(l+b)=168 cm

2(3x+X)=168 cm

2(4x)=168 cm

8x=168 cm

$x = \frac{168}{8} \\ x = 21$

Therefore, length=63 m and breadth=21 m

Answer 2

Answer:

L=63cm ; B= 21cm

Step-by-step explanation:

let, breadth of the park be x.

     length=3x

APS, perimeter of the park= 2(l+b)

                                  168= 2(3x+x)

                                  2(4x)= 168

                                   8x=168

                                    x=168/8

                  therefore,x=21cm

hence, length= 63cm

           breadth=21cm
