the answer to this question is letter a
Answer:
(Measure ) L+W : 11 and 8 inches.
These L + W measures are of each triangle and when either halved as proven below will show (A): 44inch^2
Step-by-step explanation:
Two congruent triangles of 44 sq inch = base 8 height 11
or base 11 height 8
Finding that both numbers find the same area.
Note for future areas either measure for triangle base + height
8 x 11 or 11 x 8 = 88 when halved its the same answer.
where 7 x 10 = 35
13 x 10 = 65
and so on;
No other number multiplies its length and height to show 44
One gallon per every 16 minute. 8g - 5g = 3g
48 minutes ÷ 3gallons = 16 minute per reduced gallon.
Solution :
We have to prove that 
(De-Morgan's law)
Let 
then 
and 
and so 
and 
.
Thus, 
and so 
Hence, 
.........(1)
Now we will show that 
Let ⇒
Thus x is present neither in the set A nor in the set B, so by definition of the union of the sets, by definition of the complement.
and 
Therefore, 
and we have .............(2)
From (1) and (2),
Hence proved.
