The diagonal is 13 and the length is 12. You need to find the width and the three sides make a right triangle. For a right triangle, the sides are a^2 + b^2 = c^2. (The diagonal is the c^2). So ...
a^2 + b^2 = c^2
a^2 + 12^2 = 13^2
a^2 = 13^2 - 12^2
a = sqrt(13^2 - 12^2)
a = 5 = width

c² = a² + b²
c² - a² = b² . . .Use this formula
- - - - - -
± â(13²) - (12)² = âb²
± â169 - 144 = âb²
± â25 = âb²
± 5 = b
The width is ± 5 inches

the diagnal is the hypotenue.
a^2 + b^2 = c^2
12^2 + b^2 = 13^2
c^2 = 25
c = 5
the width is 5

width = sqrt.(daigonal^2 - length^2)
=sqrt.(169-144)
=sqrt25
=5 in
