Answer is 40km
Explanation:
So in this question we can use a proportion
Since
28km is 70% we can write it equal to 70%
28=70
and since 100% is unknown we can write it equal to x
100=x
Then we put it in proportion form
28/x=70/100
Then cross multiply and divide
28(100)/70=x
Which would equal 40
Let the breadth be x
length=x+8
according to the question
area of the pool = l*b
105=x*x+8
if u solve this equation further u will get the answer
Answer: B= 11
