Answer:
Perimeter = 2 ( length + width )
Given ,
Perimeter = 15 cm
width = 4 + ( 1 / 5 ) cm = 21 / 5 cm = 4.2 cm
Hence ,
15 = 2 ( length + 4.2 )
length = 7.5 – 4.2 = 3.3 cm .

Answer:
I think this answer is 3.3 cm
Step-by-step explanation:
perimeter= 15cm
width =4×1/5 cm
perimeter = 2×(l+b)
15 =2×(l +21/5)
15 = 2×(l+4.2)
15/2 =l + 4.2
15/2-4.2/1 =l
15/2 - 8.4 /2 =l
6.6/2 = l
3.3
