Answer:
14.21 units (14.2)
Step-by-step explanation:
Formula for area is W(L) or width multiplied by length.
The formula for finding the length of a rectangle's diagonal is :
d = 
Now we solve for d.
d = 
= 
≈ 14. 21267
≈ 14.2

Just asking. How are we supposed to answer this without some sort of picture with a graph or something? :/
Answer:

Step-by-step explanation:
<u>Area of a rectangle</u>
A rectangle of width W and length L has an area of:
A = W.L
The given rectangle has a length of L=10 inches and a width of W=8 inches, thus its area is:
A = 8*10 = 80

If each corner is cut by a square of x*x, then the total area will be:

The new area is
square inches
