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

Since he sold it for $75 more,
% Mark Up = Mark Up/ Cost Price x 100%
% Mark Up = 75 / 125 x 100% = 0.6 x 100% = 60%
Percent Mark Up = 60%
Hope this helps :)
