5 * 3 does not tell you the total number of flash cards in 5 piles because you don't know how many cards are in each pile.
Mark me Brainliest pls!!!! It will help me rank up!
First you need to find the second base (b2) by plugging all the values into the area of a trapezoid formula.
A= 1/2 (b1+b2)h
After plugging it in you will find that b2= 21.3.
The questions is asking perimeter so you add all the sides together...
14.4+18.5+14.7+21.3= 68.9 ft
Hope it helps
