Rectangles ABCD and QRST are similar A,B,C,D correspond to Q,R,S,T. Find AD 📐
Step 1: Find the scale factor using corresponding sides you know.
AB corresponds to QR: AB = 12, QR = 5
Scale factor = 12/5
Step 2: AD corresponds to QT. QT = 10
AD = 10 × (12/5) = 24
What's trick for keeping similar figure correspondences straight?

3x + 6y = 63 — No Math, Just Context
3x + 6y = 63. No solving required here just understanding what each piece represents 🧩
x = number of sides of Figure A
y = number of sides of Figure B
3x + 6y = total perimeter (63 inches)
So 3x = perimeter of Figure A, and 6y = perimeter of Figure B.
