The maximum area of a rectangle whose two vertices lie on th x-axis and two on the curve $y = 3 - |x|, -3\leq x \leq 3$ is : |
9 \(\frac{9}{2}\) 3 none of these |
\(\frac{9}{2}\) |
The correct answer is Option (2) → \(\frac{9}{2}\) Area: $A = 2x (3 - x)$ $A' = 2x (3 - x) - 2x$ $x = 3/2$ Maximum area of the rectangle occurs when $= 3/2$ maximum area = $2.[3/2][3-\frac{3}{2}]=9/2$ sq. units |
