I just answered this ...
the first thing we notice : the quadrilateral has 2 pairs of equally long sides with 2 angles being openly 90°.
so, we are dealing with a rectangle here.
we know that one pair of the sides (NK = LM) are 24 cm long.
and we know that KL:LM = 3:4.
that means that the pair KL = MN are the shorter sides of the rectangle. and their length is according to the ratio 3/4 of NK=LM.
3/4 × 24 = 18 cm
the area of that rectangle is therefore
18 × 24 = 432 cm²
Answer:
or 6.75

Answer:
18%
Step-by-step explanation:
Express the ending population as a percentage of the starting population:
270000 divided by 330000=0.82
0.82 *100=82
subtract from the 100% we started with to get the percent decrease:
100% - 82% = 18
