A= anl, where
A = area
a = apothem
n = number of sides
1 = length of sides
If a regular polygon has an area of 180 cm2, an apothem of 6 cm and sides 12 cm in
length, how many sides does it have?

5 sides

Step-by-step explanation:

Area=1/2aP

180=1/2(6)(12x)

3(12x)=180

36x=180

x=5

answer: 177/8

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
