The Unique Shape Theorem states that all regular polygons with the same number of sides are similar to each other. And the immediate result of this theorem is that there is one unique shape for them.
Answer:
D
Step-by-step explanation:
The perimeter P of a rectangle is calculated as
P = 2l + 2w ( l is the length and w the width ) , then
2l + 2(9) = 5364
2l + 18 = 5364 ( subtract 18 from both sides )
2l = 5346 ( divide both sides by 2 )
l = 2673
Then
A = lw = 2673 × 9 = 24057 m² → D
