Application +4 | -1

Consider a rectangle whose length is increasing at the uniform rate of

2 \mathrm{~m} / \mathrm{sec}

, breadth is decreasing at the uniform rate of

3 \mathrm{~m} / \mathrm{sec}

and the area is decreasing at the uniform rate of

5 \mathrm{~m}^2 / \mathrm{sec}

. If after some time the breadth of the rectangle is

2 \mathrm{~m}

then the length of the rectangle is

View answer and explanation

Correct option: D

3 \mathrm{~m}

Option D (

3 \text{{ m}}

) is correct because the length of the rectangle is calculated to be 3 meters when the breadth is 2 meters.
