In unit of batches over days, let r be the planned rate and R be the actual increased rate. The difference between R and r is described as 10 shirts per day.
R-r=10
Rate Time Batches
Planned r 8 1
Actual R 7 1
![\left[\begin{array}{c}r=1/8&R=1/7&R-r=HowManyBatchesInTenShirts\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7Dr%3D1%2F8%26R%3D1%2F7%26R-r%3DHowManyBatchesInTenShirts%5Cend%7Barray%7D%5Cright%5D)
, the number of batches equivalent to 10 shirts.

OneBatch=560*Shirts
Hope This Helps!!!
C(25,10)= 3268760
P(25,10)=11861676288000
hope it helps but these are very big numbers :d
Answer:
I cant help unless i have workable units (0.5) is not a point
but im guessing that you were trying to say (0,5) in which case its
7.07106781187
its a triangle
5 on one side
5 on the other
solve for the hypotenuse
hypotenuse = 
hypotenuse = 7.07106781187
I hope this helps!
Take some points
As here < sign present line will be dashed and shading should be done below the line
