The answer:
0=cos^-1 (0.9326)
0=21.156
Nearest tenth:
0=21.2
The tenth is rounded to 2.90 and the one is rounded to 2.920. Hope it helps!:-)

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
