Simply use Pythagoras theorem....
25^2 - 20^2 = 625 - 400= 225
taking square root
width= √225 = 15 inch

Step-by-step explanation:
(diagonal)² = (length)² + (width)²
(25)² = (20)² + (width)²
(width)² = (25)² - (20)²
(width)² = 625 - 400 = 225
width = √225
= 15 inches
So , David's study table is 15 inches wide .
