Step-by-step explanation:
Taking the triangle ADC, we have 0.67 as the hypotenuse which is the diagonal of the rectangle. Since AD=BC=0.32 and looking at the triangle, we only have one side missing.
By using Pythagorean Theorem:
a² + b² = c²
Where c is the hypotenuse, a and b are the two other sides.
Hypotenuse is given, one side is given, we are now left with one unknown and that is side AB.
[tex]side \: ab = \sqrt{ {0.67}^{2} - {(0.32)}^{2} } \\ = \sqrt{ 0.4489 - 0.1024} \\ = \sqrt{0.3465} \\ = 0.59[/tex]
