Step-by-step explanation:
let side of square be 'a'
let length be 'l'cm & breadth be 'b'cm
area of square = area of rectangle
a×a=l×b
30×30=l×20
l=45cm
perimeter of rectangle is 2(l+b)
=2(45+20)
=2×65
=130cm

Step-by-step explanation:
area of square= side× side
30 ×30cm
900cm^2
area of rectangle =900cm^2
l ×b =900
l ×20 =900
l =45cm
now,perimeter =2(l+b)
2(45+20)
2×65
130cm.
