If Lana's age is L, her youngest sister is L/2 (or 0.5L) and the twins L-2. Add all these together (remember that there are two sisters who are L-2 years old):
0.5L + L-2 + L-2 + L = 45
Simplify the L's by adding them all together, we get:
3.5L - 2 - 2 = 45
3.5L - 4 = 45
Now add 4 to both sides:
3.5L = 49
Now divide both sides by 3.5
L = 49/3.5 = 14. Now we know that Laura is 14, so her youngest sister must be 7.

The Mode is 10 as it is the most repeated number.
(4/2)^2*3.4*4
2^2*3.4*4
4*3.4*4
13.6*4
54.4
(4/2)^2*3.4*4
2^2*3.4*4
4*1.7*4
6.8*4
27.2
the answer is 54.4 or the answer is 27.2, i can't quite figure it out but those are my best guesses
We are asked to find the area of the base or the side with the dimensions 4 and 2. The length would be the longest side and the width is the shorter side. The area is calculated as the product of length and width.
Area of base = 4 x 2 = 8 square units.
Therefore, the correct answer is B.
