Answer:

Perimeter = 44

2 (L + b) = 44

L + b = 22

L = 22-b.         (1)

(L+4)(b+2)= Lb+72

Lb + 2L + 4b + 8 = Lb+ 72

2L + 4b + 8 = 72

2L + 4b = 72 - 8

2(L + 2b) = 64

L + 2b = 32

Substitute for L

(22-b) + 2b = 32

22 + b = 32

b = 10 cm

L = 22- b

= 22-10

= 12 cm

So:

Length= 12 cm

Breadth= 10cm

Hope it helps!!!
