To solve for what one of the sides is, basically add all of the sides of this irregular shape and make it equal to the total perimeter. d + 15.4 + 16.2 + 28.7 = 82 d + 60.3 = 82 d = 82 - 60.3 d = 21.7 cm. The solution for d is that it is 21.7 cm.
All you have to do is add up the side lengths we already know then subtract by the perimeter. 60.3 is the side lengths all together that we know 82-60.3=21.7 Hope this helped!!
