The new dimensions or scale according to the information provided is now 4m/2units. See the explanation below.
<h3>What is the explanation justifying the above answer?</h3>
According to the given graph, the perimeter is 12 units. The current scale is 48m to 12 units (or 4m to 1 unit). Hence the new scale will be twice the original graph.
That is:
2m/1 units = (2m x2)/ 1unit x 2
= 4m/2units.
See the attached and enlarged new image.
Section II
The dimensions of the picture are as follows:
Length: acm
Width: bcm
Thus,
Length ⇒ acm/lft = lcm/5ft
L = (5a)ft
Width: ⇒ bcm/wft = Lcm/5ft
w = (56) ft
Another picture:
Length: 5a/8 cm
Width: 5b/8 cm

Answer:
3.75 cups
Step-by-step explanation:
30/8=3.75
The answer would be B.
For these, you plug in 8 where there ia a variable. 2(8)-1=15
Answer:
B) BC'= 8, m A'= 28°
Step-by-step explanation:
When dilating a figure, it increases its size or decreases. In this case, as it is dilating by a factor of 1/2, you can assume it decreases.
To find the value of the new figure, A'B'C', you have to multiply the factor times the lengths of the triangle, or, the only one they are asking for in this case, the length BC':
- BC' = BC×1/2
- BC' = 16×1/2
- BC' = 8
The angles, otherwise, do not change. When figures are dilated, they are similar. The properties of similar figures are that they have congruent angles, therefore, the same angles. They do not have any effect caused by the factor, so m A' stays at 28°.
