Step-by-step explanation:
Perimeter = 2(l+b)
l = (4x-4)
b = (2x-9)
106 = 2(4x-4+2x-9)
106/2 = 4x+2x-9-4
53= 6x-13
66=6x
x = 66/6
x = 11
l = (4×11)-4
= 44-4
= 40
b = (2×11)-9
= 22-9
= 13

Answer:
length= 42cm
breadth= 14 cm
Step-by-step explanation:
As perimeter of rectangle is 2(l+b)
106. = 2(4x-4+2x-9)
106/2. =. 6x-13
53 + 13. = 6x
69 / 6. = x
x= 11.5 cm
length= 42cm
breadth= 14 cm
