Rectangles that are 5×20, 6×12, or 8×8 will satisfy your criteria. The sum of the areas of those is 236 units².
_____
20×5 and 12×6 rectangles are also "cool", but their areas are not different from those already counted.
Answer:
1399/200 699.5%
Step-by-step explanation:
Each element is 2/3 times the previous one, so that's a geometric sequence.
6×(2/3)=4, 4×(2/3)=8/3, 8/3×(2/3)=16/9, 16/9×(2/3)=32/27
Answer: 6, 4, 8/3, 16/9, 32/27
8(2)-y=4
16-y=4d
-1y/-1=-12/-1
y=12
(16,12)
