Two lengths and two widths will surround the window
2(5) + 2(8) = 26 ft.

When you go around something - you are looking at perimeter. Perimeter means the distance around. You want to put a frame around the window so you need to figure out the perimeter of the window.
Your window has a top and bottom the same size which is 5 feet each
Your window has two side also the same - 8 feet
Altogether to go around your window you need:
bottom 5'
top 5'
side 8'
other side 8'
TOTAL 26 feet.
When you figure out the perimeter of shapes that have straight sides just add up all the sides. This would be the formula for a 6 sided shape. (P stands for perimeter, s for sides)
P = s1 + s2 + s3 + s4 + s5 + s6

It's just the perimeter.
p=2l+2w=2*5+2*8=10+16=26 feet

If the wood is infinitely thin, 26 feet. Mathematicians make lousy carpenters.
