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.
I hope this helps!! ^-^

Simplify 9x2y· 3+3x2y· 3−2· 1· y· 3: 36x2y−6y
Answer: x = 5
Step-by-step explanation: First distribute the 3 to get 9x +21 = 3x +51, then subtract 3x and 21 from both sides to get 6x = 30, and finally divide by 6 on both sides to get x = 5.

Answer:
16/13
Step-by-step explanation:
Use a calculator lol
Can I have brainliest please
S=S1+S2, where S1=12*4=48 cm², S2=0.5*(12-3-3)*(8-4)=12 cm².
S=48+12=60 cm²
