Answer:
the rate of changes of the area of the triangle
Step-by-step explanation:
<u>Explanation</u> :-
The area of triangle( A) = ..........(1)
Let 'b' be the base and 'l' be the length of the triangle
The base of a triangle is shrinking( means decreasing) at a rate of 11 cm/s
that is
The height of a triangle is increasing at a rate of 11 cm/s
that is
Given h= 10cm and b = 8cm
<u>The rate of change of triangle </u>
applying uv formula
Differentiating equation (1) with respective to 't'
substitute all values in above equation, we get
h= 10cm , b = 8cm , and
After simplification , we get
