Divide 124 cm by 4 = 31 cm
 
each side of the square is 31 cm 
 
For the AREA OF THE SQUARE multiply ~
 
31 cm * 31 cm = 941 cm
 
the answer is 941 cm

Hello Jill,
 
It should be 961 sq cm
Oh thank you - you are absolutely right..... I was did it way too quickly thinking I had it without trying. I appreciate that you corrected me. It will make me slow down and check my work - like I instruct my students ????  (embarrassed )

Each side = x
4x=124
x=31. cm
 
So, side of the square= 31cm
 
Area of the square= 31*31
                           =961 sq cm
