take breadth as x
length as x+4
perimeter = 2× (Length +breadth)
84 = 2 (x+4 +x)
84 = 2x + 8 + 2x
84 = 4x + 8
84-8 = 4x
4x = 76
x = 19
breadth = x = 19
length = x + 4 = 19 +4 = 23
length as x+4
perimeter = 2× (Length +breadth)
84 = 2 (x+4 +x)
84 = 2x + 8 + 2x
84 = 4x + 8
84-8 = 4x
4x = 76
x = 19
breadth = x = 19
length = x + 4 = 19 +4 = 23

Answer:
Step-by-step explanation:
Let breadth be x m, length is (x+4)m
Perimeter is 84m
2x+2(x+4)=84
x=19
So, breadth and length are 19m and 23m respectively
