Answer 2

Answer:

$perimeter \: of \: a = 3 \times perimeter \: of \: b$

Step-by-step explanation:

$let \: side \: of \: square \: a \: is \: x \\ and \: side \: ofsquare \: b \: is \: y\\ area \: of \: square \: a \: \\ = 9 \times area \: of \: square \: b \\ {x}^{2} = 9 {y}^{2} \\ x = 3y \\ perimeter \: of \: a = 4x \\ perimeter \: of \: b \: = 4y \\ \frac{perimeter \: a}{perimeter \: b} = \frac{4x}{4y} \\ = \frac{x}{y} \\ \frac{3y}{y} \\ = 3 \\ perimeter \: of \: a = \\ 3 \times perimeter \: of \: b$
