Question

each side of a sqare field is 20m there is another field and ratio of their adjecent sudes is 3:1 if the perimeter of both fields are same find the dinensions of the rectangular field

Answer 1

Hiiii,
the perimeter of square field=4a=4×20=80m
the perimeter of square field =the perimeter of rectangular field.
breadth=x and length=3x
2(l+b)=2(3x+x)=2×4x=8x
but perimeter of rectangular field =80
x=80/8=10m
length=3x=30m
bredth=x=10m
