Haylie Rowe · Answer 1

First get the length of the side the was cut (Hypotenuse).

We can use Pythagorean theorem: a^2+b^2 = c^2

a = 8, b = 3 = 1.5, c = ?

plug into forumla

8^2 + 3^2 = 73

a=8,

b=1.5,

c = sqrt (73) or 8.5

Now add all sides together to get perimeter ...

8+3+8.5 = 19.5

The perimeter of each sheet is 19.5in.
