( 90 m ) x ( 0.9 yds/m ) = 81 yds
( 126 m ) x ( 0.9 yds/m ) = 113.4 yds
------------
+81%2A113.4+=+9185.4+ yds2
------------
The number of pallets needed is:
+9185.4+%2F+90+=+102.06+ pallets
------------
The total cost is:
+205%2A102.06+=+20922.3+ ( cost / pallet ) x ( number of pallets )
$20,922.30

            Tutor @josmicely INCORRECTLY converted meters to yards.


90 meters  = (about) 90%2F0.9 = 100 yards.

126 meters = (about) 126%2F0.9 = 140 yards.


The area in square yards = 100*140 = 14000 square yards.


In terms of pallets, the area is  14000%2F90 = 155.56 pallets (approximately).


The cost = 205*155.56 = 31890 dollars.    ANSWER  (estimation)

Solved.
