1.	At a given instant, the legs of a right angled triangle are 8 cm and 6 cm. If the first leg decreases at the rate of 1 cm/sec and the second leg increases at the rate of 2 cm/sec respectively, then the rate of change in the area after 2sec is equal to ( in cm2/sec)
Answer» At a given instant, the legs of a right angled triangle are $8 cm$ and $6 cm .$ If the first leg decreases at the rate of $1 cm / sec$ and the second leg increases at the rate of $2 cm / sec$ respectively, then the rate of change in the area after $2 s e c$ is equal to $({in cm}^{2} / sec)$
