If the side of a squere is 12 cm find area

area of a square =side^2

measurement of a side= 12 cm

A = side * side

A = ( 12*12) cm

A= 144 cm^2

so area of a square is 144 cm square

if the square is perfectly 12 cm on each side take; 12×12=144 so the area of the square would be 144cm because you are doing L×W=Area
