The base of a triangle is shrinking at a rate of 1 cm/min and the
height of the triangle is increasing at a rate of 5 cm/min. Find the rate at which the area
of the triangle changes when the height is 22 cm and the base is 10 cm

Respuesta :

Answer:

20cm^2/min

Step-by-step explanation:

area=1/2 × (base×height)

1)differentiate area with respect to time

2)rate of change of height and base is given(take decreasing rate as negative).

3)put the values of height and base.

4)obtain the rate of change of area
