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
Step-by-step explanation:
WYXV is quadrilateral.
the reason are the undefined angles at W and V (they are equal, but not necessarily 90°, so the shape could shrink or extend between W and V)
ABCD is a rectangle.
AB and CD are parallel and equally long. and C is 90°.
that means then that the other angles must be 90° too, or either the parallel or equally long criteria would be violated.
PQSR is a parallelogram.
PQ and RS are parallel and equally long.
that means that PR and QS must also be parallel and equally long. we just don't know the angles, they could be anything. and therefore this is not a rectangle but a more generic parallelogram.
Answer:
