What is the width (w) of the pound, in feet?

12

Step-by-step explanation:

1. Use the Pythagorean Theorem to solve: a^2+b^2=c^2.

Here you are given the hypotenuse (which is always c in the formula), and one other leg that could be either a or b.

2. Plug these numbers into the formula and evaluate them.

a^2 + 16^2 = 20^2

16 x 16 =256

20 x 20 = 400

So that gives you a^2 + 256 = 400.

3. Subtract 256 from both sides and take the square root of the result.

400 - 256 = 144

a^2 = 144

= 12

∞ this is your sign
