Question

The length x of rectangle is increasing at the rate of 3cm/ sec and width y is increasing at the

rate of 2cm/sec. Find the rate of change of its area when x = 10cm and y = 6 cm.​

Answer 1

Answer:

sorry I didn't know this answer

Answer 2

Step-by-step explanation:

Rate of change of area is 18cm²/sec

Explanation

X=3cm/sec

y= 2cm/sec

area in the first second= 2×3= 6cm² - 1

area when X=10cm and y=6cm = 10×6 = 60cm² -2

rate of change of area= final area- initial area/time taken to reach that are = 60-6/3= 54cm²/3 = 18cm²/sec
