Two common envelopes sizes are 3 1/2 in. times 6 1/2 in. and 4 in. times 9 1/2. Are these envelopes similar? Explain.

Whatever happened to please?

 

Two common envelopes sizes are 3 1/2 in. times 6 1/2 in. and 4 in. times 9 1/2. Are these envelopes similar? Explain.

 

6.5/3.5 = 1.8571428571428571

9.5/4 = 2.375

NOT the same answer.

 

The sides of the rectangle are NOT in the same ratio so the envelopes are NOT a similar size.
