Answer:
square covers more area by 4 cm sq
Step-by-step explanation:
side of square=10cm
perimeter of square=4Xside
4 X 10=40
p of square = p of rectangle
length of rectangle= 12cm
breadth= b
perimeter of rect=2(l+b)
40=2(12+b)
40=(12+b)
2
20=(12+b)
20-12=b
b=8cm & l=12cm
area of square=s X s
10 X 10 =100cm sq
area of rectangle= l X b
12 X 8= 96cm sq
