The rate of increase of x when A = 25 is 0.0006 cm/s.
Step-by-step explanation:
Area of a square A =
sq. cm
So, x =
cm
It is given that the area is increasing at the rate of 0.03
/s.
Therefore,
We need to find the rate of increase of x when A = 25.
Now, substituting the values of A and
, (1) becomes
= 0.0006
Hence, the rate of increase of x when A = 25 is 0.0006 cm/s.
