Answer:
Length = 19, Breadth = 15
Step-by-step explanation:
Let L represent the length.
The breadth is then L - 4.
The perimeter is equal to twice the length, plus twice the breadth:
2L + 2(L - 4) = 68
2L + 2L - 8 = 68
4L - 8 = 68
4L = 76
L = 19
Then, the breadth is L - 4 = 19 - 4 = 15
Solution: Length = 19, Breadth = 15
Check: 19 + 15 + 19 + 15 = 68

breadth=15, length=19
