Answer 2

Applying the Pythagorean Theorem, the size of the TV that is 16 inches by 12 inches is: B)20 inch

Recall:

• Diagonal of a rectangle can be found using the Pythagorean Theorem given as: $d = \sqrt{l^2 + w^2}$
• Where, d = diagonal, l and w are the dimensions of the shape.

Given:

l = 16 inches

w = 12 inches

• Therefore,

$d = \sqrt{16^2 + 12^}$

$d = \sqrt{400} \\\\\mathbf{d = 20 inches}$

Therefore, applying the Pythagorean Theorem, the size of the TV that is 16 inches by 12 inches is: B)20 inch
