Question

The length and breadth of a rectangular playground are in the ratio 4:3. If the area of the playground is 30,000 m, find its length and breadth.​

Answer 1

Step-by-step explanation:

Let proportional quantity be x

Let lenght of the rectangular playground be 4x

Breadth of the rectangular playground be 3x

Therfore,Area of rectangle =length *breadth

30,000m. =4x*3x

30,000m. =12x^2

Answer 2

Answer:

Area = 30000m

L and B = 4/3

Let the length =x

So, length is 4x and breadth is 3x

First change cm To m 4x*100

And 3x 100

Area of REC = l*B

30000m=400x*300x

30000m= 1200x^2

30000/1200=x^2

25*2= x

50=x

Now, 4*50,3*50

=200m,150m
