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:

Step-by-step explanation:
Let  be the number of bags with 8 onions and let
 be the number of bags with 8 onions and let  be the number of bags with 3 onions. We have the following system of equations:
 be the number of bags with 3 onions. We have the following system of equations:

Subtracting  from both sides of the first equation, we get
 from both sides of the first equation, we get  . Substitute this into the second equation:
. Substitute this into the second equation:

Therefore, the number of 8-onion bags is:

Thus, the chef got 4 8-onion bags and 3 3-onion bags.
