Answer:
Area of Figure 1 = 48
Step-by-step explanation:
We are given CD and EF. We can use this to find the scale factor between the two shapes.
The scale factor from Figure 1 to Figure 2 is 7/4.
The scale factor from Figure 2 to Figure 1 is 4/7.
Perimeter of Figure 2: 16 × 7/4 = 28cm, which is correct.
Area of Figure 1: 147 × (4/7)^2 = 48cm^2 We square the SF as we only worked out the Length Scale Factor. The Area Scale Factor is the Length Scale Factor squared.

Answer:

Just do long division and remember to keep the decimal points aligned.
It is possible to convert a fraction to a decimal in mathematics. First, -3/11 is a fraction. To convert a fraction which is -3/11, divide 3 by 11 which you get .272727... and you get the idea. The '27' repeats. Therefore, the answer would be -.27 with a <span>Vinculum symbol which is a horizontal line above the number to indicate its repeating. Also, don't forget to put a negative sign!</span>
