Find the area of the regular polygon. give the answer to the nearest tenth.

dodecagon with a perimeter of 108 cm

A regular dodecagon is a polygon with 12 equal sides.
Length of each side = 108/12 = 9 cm.

Length of the apothem = (9/2)/tan 15 = 9/2tan 15 = 16.79 cm

Area of each triangle = 9/2(16.79) = 75.57 cm^2

Therefore, area of the dodecagon = 12(75.57) = 906.9 cm^2

2 minus one-fourth greater-than one-half m.

Step-by-step explanation:

Let Martin's dog eats is 'm'.

So, Felicity's dog eat at least cup more than .

Now, it says Felicity's dog eats 2 cups of dog food

So, we can set up inequality as

2>

We can rewrite it as

>

So, last option is right.

2 minus one-fourth greater than one half m.
