plz mark me as the brainliest

Answer 2

Answer:

139/3 cm or 46 1/3 cm

Step-by-step explanation:

$perimeter \: of \: rectangle \: = 2(x + y) \\ x = length =12 \frac{1}{2} \: \: and \\ y = breadth = 10\frac{2}{3} \\ x = \frac{(12 \times 2) + 1}{2} = \frac{25}{2} \\ y = \frac{(10 \times 3) + 2}{3} = \frac{32}{3} \\ perimeter \: = 2( \frac{25}{2} + \frac{32}{3} ) \\ = \frac{25}{1} + \frac{64}{3} = \frac{(25 \times 3) + 64}{3} \\ = \frac{65 + 74}{3} = \frac{139}{3} \\ = \frac{138 + 1}{3} \\ = 46\frac{1}{3}$

I hope you are clear if not just comment and don't forget to mark my answer as the brainliest.
