Answer:

Use an ruler if you must listen to explanation.

Step-by-step explanation:

So this is actually very easy so it already tells you the Width= Feet is 80. But the Length = Feet is 6 greater any time you see something that says Number? Greater it means Multiply so multiply 6x80=480 so your length will be 480 Ok that's true But! The Width isn't answered your paper/screen Says, The perimeter of a rectangular outdoor patio is 80 ft. The length is 6 feet greater than the width what are the dimersions of the patio. Dimersion's what is it? The number.

So your confused?

Here are a list of things you can use,

A ruler

A protractor

Or A Tape Measuerer

Pardon if spelled wrong.

Anyway the perimeter is 80 ft.  Here's what i would do i would use a ruler and see how long the width is then times that with 6 and you should get your answer i cannot use my ruler because picture is to small even when clicked this should help you.

Hope this helped!

Answer:

It will take Madeline 13 minutes to heat her hot tub from 93° to 103°

Step-by-step explanation:

Hot tub is 70.15 cubic feet

70.15 cubic feet = 524.76 gallons

{\text{apothem}}={\frac  {s}{2\tan({\frac  {180}{n}})}}

n is the number of sides of the shape, so apothem will always be

side length/2tan(30) on a regular hexagon

Apothem comes out to 2.598 multiplied by perimeter yields 23.3827 (area of base)
