Answer:
Length =5:3
suppose the length and width of the field be 5xm and 3xm respectively
Width =42m
3x=42
x= 42/3
=14
∴length=5x=5×14=70m

Answer:
2.5 m
Step-by-step explanation:
Ratio = 5:3
Thus, Length = 5x
Width = 3x
Perimeter (given) = 8m
→ Perimeter = 2(l+b)
→ 8 = 2(5x+3x)
→ 4 = 8x
→ x = 1/2
Length = 5x = 5/2 = 2.5 m
