Area = length × width.<br><br>
&bull; \( \frac{7}{10} \times \frac{2}{5} = \frac{7 \times 2}{10 \times 5} = \frac{14}{50} \)<br>
&bull; Simplify: divide numerator and denominator by 2.<br>
&bull; \( \frac{14}{50} = \frac{14 \div 2}{50 \div 2} = \frac{7}{25} \)<br><br>
Final Answer: \( \frac{7}{25} \) m&sup2;
