Hi



a rectangle has a diagonal of 5in and a length of 4in.

Pythagorean Theorem:  a^2 + b^2 = c^2

Let x be the width

4^2 + x^2 = 5^2   |Diagonal being 5"

x^2 = 25-16

x^2 = 9in^2

x = ± 3

Width = 3in   |Tossing out the Negative Solution of -3  for Length

Wish You the Best in your Studies.

That's one of the few Pythagorean Triples, a 3-4-5, which makes the width, 3 inches.
