Answer:
A = 12
Step-by-step explanation:
Given A is inversely proportional to B then the equation relating them is
A = 
To find k use the condition when A = 4, B = 36 , then
4 = 
( multiply both sides by 36 )
144 = k
A = 
← equation of variation
When B = A , then
A = 
( multiply both sides by A )
A² = 144 ( take square root of both sides )
A = ± 
= ± 12
Since A is a positive number then A = 12
