Answer:
side of square is 31 cm
Step-by-step explanation:
perimeter of rectangle =2(40+22)
=2(62) = 124
perimeter of square =perimeter of rectangle
4s = 124
s = 124÷4 = 31cm
area of square = s*2 =(31)*31 = 961 cm*2
area of rectangle =l*b = 40*22 = 880 cm*2
therefore,
measure of each side= 31 cm
square encloses more area and by 81 cm*2
