<u>Answer: </u>
Chance bought a surf board for 249. Now it's on sale for 221.10 and 11.20% is the discount.
<u>Solution:
</u>
Step 1:
Bought price= RS.249
Sale price=RS.221.10
Step 2:
Discount = bought price - sales price
Discount = 249 - 221.10
Discount = 27.9
Step 3:
Discount Percent = 
Substitute the value for Discount which we found in step 2 in the above formulae
Discount Percent = 
On simplification, we get

Discount Percent = 11.20%
Result:
Hence from the given data, we got the discount percent is 11.20%
Answer:
32
Step-by-step explanation:
We let the length of the square be l, the diagonal be z and the area be A.
Then by Pythagoras theorem;

The are of a square of length l is given as;

Combining these two equations yields;


Next, we have been given;

We are required to find;
when z = 4
By chain rule;

Differentiating
with respect to z yields;

Therefore,
= 8z
When z is 4m the area of the square will be increasing at a rate of;
8m/min * 4m = 32
