A regular pentagon has side lengths of 14.1 centimeters and an apothem with length 12 centimeters. What is the approximate area of the regular pentagon? 288 cm2 342 cm2 432 cm2 691 cm2 EDGE

423 cm^2

Step-by-step explanation:

Area of a regular pentagon = Pa/2, where P = the perimeter and a = the apothem.

We can find the perimeter by

P = 5s where s is the side length since the pentagon is regular

P = 5( 14.1)

P = 70.5

A = P*a/2

   = 70.5 ( 12)/2

  =423 cm^2

Step-by-step explanation:

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
