The altitude of a triangle is increasing at a rate of 1 cm/min while the area of the triangle is increasing at a rate of 2cm2 /min. at what rate is the base of the triangle changing when the altitude is 10 cm and the area is 100 cm2 ?

We have the area of the triangle .

Differentiating with respect to time t,

Substituting numerical values, the rate of change of base length is

40 minutes

step-by-step explanation:

add the time and multiply by 2

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
