Answer:
90.75 cm^2
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 ( b1+b2) *h
where b1 and b2 are the lengths of the bases and h is the height
A = 1/2(8.5+ 15.7) * 7.5
1/2 (24.2) 7.5
90.75 cm^2
The unit rate in minutes per meter for filling the given aquarium to a depth of 2/4 meters will be 8 minutes per meter.
We have,
Time taken to fill an aquarium to a depth of m = 4 minutes,
So,
Time = 4 minutes,
And,
Depth = m,
Now,
The unit rate in minutes per meter,
So,
We will Now convert given depth fraction,
i.e.
Depth = = 0.5m,
So,
It takes 4 minutes to fill a half meter,
Then,
To fill a meter it will take = = 8 minutes
So,
The unit rate in minutes per meter is 8 minutes per meter.
Hence we can say that the unit rate in minutes per meter for filling the given aquarium to a depth of 2/4 meters will be 8 minutes per meter.

Answer:
15 meters
Step-by-step explanation:
The diagram of the problem is attached below in the first image.
Chords KM and LN (which is the diameter) intersect at X.
Theorem: If the diameter is perpendicular to a chord, it bisects the chord.
Therefore:
LN divides KM into equal parts of 6 meters,
Applying the theorem of intersecting chords:
KX*XM = LX*XN
6*6=3*XN
3*XN=36
XN=12
Next, we find the length of the diameter LN
LN=LX+XN
=3+12
=15 meters
The diameter of the completed circle is 15 meters.
