Question

Find the width of a rectangle if the diagonal is 19 and the length is 16

Answer 1

≈10.25

Explanation:

use the Pythagorean Theorem: a² + b² = c²

c is the hypotenuse, the diagonal, or the longest side of the triangle

a = 16

b = ?

c = 19

(16)² + b² = (19)²

256 + b² = 361

b² = 105

b = √105 ≈ 10.25
