Question

each side of a square field is 20 m this is another field and ratio of their adjacent sides is 3 is to 1 if the perimeter of both the fields are same find the dimensions of the rectangular field

Answer 1

perimeter of square field =4×20
80m
given that the perimeter of square and rectangular field are same
so, let the adjacent side of rectangular field be 3x and x
2(l+b)=80
2×4x=80
8x=80
x= 80/8
x= 10
so length of rectangular field is 3×10=30m
breadth is 10 m

Answer 2

bhai perimeter of sqaure feild = 80 cm

take the take the ratio given as 3x ,1x.

then perimeter of rect. = 2 * (3x + 1x)

80 = 2*4x

80=8x

x=10

3x =30 and 1x = 10

good luck
