Let Breadth of rectangle be 'b'

According to QUESTION now :

→ Perimeter of rectangle = 2(Length + Breadth)

Plug in the given values in above formula :

→ 72 cm = 2(20 + b)

→ 72 = 40 + 2b

→ 72 - 40 = 2b

→ 32 = 2b

→ b = 32 ÷ 2

→ b = 16 cm

Therefore, breadth of rectangular field is 16 cm.

V E R I F I C A T I O N :

➻ 72 = 2(20 + b)

➻ 72 = 2(20 + 16)

➻ 72 = 40 + 32

➻ 72 = 72
