Answer:
14
Step-by-step explanation:
Original Width: 10.5
Original Length: 12
Scaled Width: 3.5
Scaled Length: ?
We will be using x to find the unknown scale multiplier
Solving for x:
3.5=10.5/x
Multiply both sides by x:
3.5•x=10.5/x•x
3.5x=10.5
Divide both sides by 3.5:
3.5x/3.5=10.5/3.5
x=3
To find the length, we need to divide the original length by 3:
12/3=4
The area of the scaled model (Scaled Length*Scaled Width):
Scaled Width: 3.5
Scaled Length: 4
3.5•4=14
Hope this helped!
