Answer:

the answer will be
Perimeter of rectangle = 72 cm.
Sum of adjacent sides = 36 cm
So the rectangle could have the following length and width
35 cm x 1 cm and its area = 35 sq cm
34 cm x 2 cm and its area = 68 sq cm
33 cm x 3 cm and its area = 99 sq cm
32 cm x 4 cm and its area = 128 sq cm
31 cm x 5 cm and its area =155 sq cm
30 cm x 6 cm and its area = 180 sq cm
29 cm x 7 cm and its area = 203 sq cm
28 cm x 8 cm and its area = 224 sq cm
27 cm x 9 cm and its area = 243 sq cm
26 cm x 10 cm and its area = 260 sq cm
25 cm x 11 cm and its area = 275 sq cm
24 cm x 12 cm and its area = 288 sq cm
23 cm x 13 cm and its area = 299 sq cm
22 cm x 14 cm and its area = 308 sq cm
21 cm x 15 cm and its area = 315 sq cm
20 cm x 16 cm and its area = 320 sq cm
19 cm x 17 cm and its area = 323 sq cm
18 cm x 18 cm and its area = 324 sq cm. This can be ruled as it is a square.
Answer:
Given,
area of rectangle=72cm^2
length = 9cm
for circumference we need breadth
so,
area of rectangle=length×breadth
72=9×b
breadth=8
circumference of rectangle=2(length+breadth)
=2(9+8)
=34
