Answer 1

Answer:

616 sq cm

Step-by-step explanation:

$length \: = 24 \frac{2}{5} \\ length \: with \: border \: \\ = 24 \frac{2}{5} + 3 \frac{3}{5} = \frac{122}{5} + \frac{18}{5} = \frac{140}{5} = 28 \\ breadth \: = 20 \frac{2}{5} \\ breadth \: with \: border \: = 20 \frac{2}{5} + 3 \frac{3}{5} \\ = \frac{102}{5} + \frac{18}{5} = \frac{120}{5} = 22 \\ area \: with \: frame = 28 \times 22 = 616$
