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
Well, $107 times 7 is $749, is that what ypu needed?
Answer:
Step-by-step explanation:
Find the center of the door.
70.33/2=35.165cm
Find the center of the towel rack
24.25/2= 12.125cm
The towel rack will be 12.125cm from the center of the door in either direction. To get the location of either end add 12.125cm or subtract 12.125cm from 35.165cm.
Note: I used decimals, this can also be done with fractions.
