Question

length =3(2/5)m and breadth is 4/7 m​

Answer 1

Answer:

$length = 3 \frac{2}{5} = \frac{17}{5} \\ breadth = \frac{4}{7} \\ area = l \times b \\ = \frac{17}{5} \times \frac{4}{7} \\ \frac{68}{35}$

Answer 2

$\tt length=3 \times \frac{2}{5} = \frac{17}{5} \\ \\ \tt breadth=\frac{4}{7} \\ \\ \tt \: area=l×b \\ \tt \implies\frac{17}{5} \times \frac{4}{7} \\ \tt\implies\:\frac{68}{35}$
