Answer 1

Answer:

this is the correct answer

Answer 2

$we \: know \: that \: \\ perimeter \: of \: square = 4 \times side \\ 20 = 4 \times side \\ side = \frac{20}{4} = 5 \\ so \: the \: side \: of \: square \: is \: \\ 5cm. \\ \\ for \: checking \: the \: answer \\ perimeter = 4 \times side \\ 4 \times 5 = 20. \\ so \: we \: get \: the \: answer \: \: as \\ our \: perimeter \: 20.$
