Answer:
The answer is 28.3cm
Step-by-step explanation:
You take the "new" side length, 22 cm, over the "old" side length, 1.4 cm and write the proportion 22/1.4= x/1.8 cm using x as the unknown, and 1.8 cm as the other "old" side length. Then solve. Multiply 22 x's 1.8. Then divide by 1.4. Giving us the solution x= 28.3 cm.
Hope this helps!
