Practicing Success
In a school, auditorium was used for its cultural activities. The shape of the floor of the auditorium is rectangular with dimensions x and y (x > y), has fixed parameter p. Based on the above information answer the following questions. |
The value of y, for which area of floor of auditorium is maximum is : |
$\frac{p}{2}$ $\frac{p}{3}$ $\frac{p}{4}$ $\frac{p}{16}$ |
$\frac{p}{4}$ |
p = 2x + 2y at $x = \frac{p}{4}$ → area maximum so $p = \frac{2p}{4} +2y$ ⇒ $p - \frac{p}{2} = 2y$ ⇒ $y = \frac{p}{4}$ → for max. area |
