GEOMETRY- FIND POLYGON AREA

Mathematics
1 answer:
Dvinal [7]2 years ago
5 0

Answer:

Step-by-step explanation:

The area of a regular polygon is

A=\frac{1}{2}ap where a is the apothem and p is the perimeter. Perimeter is simple: just count the number of sides the polygon has and multiply it by 3 (the length of one side).

p = 3(9) is 27 inches for the perimeter.

We have what we need now to find the area:

A=\frac{1}{2}(4.1)(27) and

A=\frac{1}{2}( 110.7) so

A = 55.35 square inches

ryzh [129]

Answer:

The number of robberies in 2014 is 108

Step-by-step explanation:

Here, we want to calculate the number of robberies in 2014

from the question, the robberies went down by 40%

Let the number of robberies in 2014 be x

Thus;

40/100 * 180

= 72

This means that the value it went down was by 72

Thus;

x = 180-72

x = 108
