Answer 1

Answer:

Step-by-step explanation:

1st find perimeter of rectangular field by formula 2 (l+b).It will come 50 m.Perimeter of another field is also 50m then.

ATP

2 (4x+x)=50m

or 8x+2x=50m

or10x=50m

or x=5m

therefore breadth is 5m and length is 4x=4×5m=20m (by taking common part to be x

Answer 2

Answer:

Step-by-step explanation:

perimeter = 50

when ratio is 4x : x  

so  4x + x = 50

x = 10
