Answer:
(4/16)^2
(3/12)^2
12/192
Step-by-step explanation:
We can write the ratio by taking the smaller length over the larger length
4 / 16
1/4
To find the area ratio
We take the scale factor and square it
I remember length is in units, area is in units ^2 so the area ratio is in scale factor squared
(1/4)^2
1/16
We can also look at the scale factor squared before we simplified it
(4/16) ^2
We also could look at the width ratio
3/12 and square it
(3/12)^2
Looking for the third choice
12/192 simplifies to 1/16
