Answer:
625 cm²
Step-by-step explanation:
rectangle length and breadth are 20 cm and 30 cm.
the perimeter of square = the perimeter of rectangle
because both are made of same wire.
4a =2(l+b).
( if l,b are length and breadth of rectangle and a is side of square)
4a = 2(20+30) =100
a= 100/4 = 25 cm
area of the square = a² = ( 25)²
= 625 cm²
