Question

The length of a field is twice its breadth. If the perimeter is 600m. Find its length and breadth.

Answer 1

Let the breadth of a field be x
So, length = 2x
Perimeter = 2(l+b)
Therefore,
2( x + 2x) = 600
2 (3x) = 600
6x = 600
X = 600/6
X = 100
So,breadth = 100
And length = 2 x 100 = 200

Answer 2

Answer:

The length of the playground is 200m and the breadth is 100m

Step-by-step explanation:

Let the length of the ground be $x$ m and the breadth be $y$ m

From the first condition,  $x$ = 2$y$  

                                     $x$-2$y$ = 0 (1)

The perimeter of a rectangular playground = 2( l + b ) (Formula)

From the second condition, 2(  $x$+$y$  ) = 600 (2)

Adding equations (1) and (2),

3$x$ =600

 $x$ =200

Substituting the value of  $x$ in equation (1),

200-2y=0,

        2y=200

           y=100

∴The length of the playground is 200m and the breadth is 100m
