Length = 5x + 4
Breadth = x - 4
Solve x:
Given that the perimeter is 72 m
Perimeter = 2( Length + Breadth)
72 = 2(5x + 4 + x - 4)
72 = 2(6x)
12x = 72
x = 6 cm
Find the length and breadth
Length = 5x + 4 = 5(6) + 4 = 34 cm
Breadth = x - 4 = 6 - 4 = 2 cm
Answer: The length is 34 cm and the breadth is 2 cm
