Area = length * width
A = 5 1/6 * 2 2/7
A = 31/6 * 16/7
A = 248 / 21 or 11 17/21 cm^2 <== oh...in a calculator u would get 11.81 (thats rounded)...but if u want it in a calculator, u will not get it in mixed number form

A rope from the top of a mast on a sailboat is attached to a point 6 feet from the base of the mast. If the rope is 24 feet long

Zanzabum

Answer: It is about 23 feet.

Step-by-step explanation:

1. Let's call x the height of the mast.

2. You know that the rope is attached to a point 6 feet from the base of the mast and the rope is 24 feet long, therefore, you can draw the right triangle shown in the figure attached.

3. To calculate x, you must apply the Pythagorean Theorem as you can see below:

$x=\sqrt{(24ft)^{2}-(6ft)^{2}}\\x=\sqrt{540ft^{2}}$
