Answer:
77
Step-by-step explanation:
b is present in both ratios, find first the LCM of 8 and 6, which is 24.
Multiply a:b=3:8 by 3 to get a:b=9:24
Similarly, multiply b:c=6:11 by 4 to get b:c=24:44
Then we conclude
a:b:c=9:24:44
Since there is no common factor among the three numbers, this is the simplest ratio possible.
If a,b and c are integers, the smallest values for a,b and c are 9,24,44.
Add up the three numbers to get the least value of a+b+c=77.

Answer:
Step-by-step explanation:
The diagram consists of different boxes if the same sizes. Each box is a square with sides measuring 1 cm. The area of each box would be
1 × 1 = 1cm^2
The area of the parallelogram is the total number of squares that it contains. To determine this, the first step is to count the total number of complete squares. Looking at the diagram, there are 11 complete squares. This means
11 × 1 = 11 square units.
The next step is to count the number of incomplete squares and divide by 2. The number of incomplete squares are 8
8/2 = 4
4 × 1 = 4 square units
The area of the parallelogram would be
11 + 4 = 15 square units
The axis of symmetry is 2 and the vertex is (2, 4).
