Answer:
Length: 16.7
Perimeter: 41.2
Step-by-step explanation:
65.13 divided by 3.9 = 16.7 which is the length. You can use this expression: (16.7 x 2) + (3.9 x 2) to get a perimeter of 41.2.
I believe it is 510 cm because a meter equals 100 cm so 210 cm times 2 equals 410 cm then multiply 45 times 2 and get 90 cm then add 410 plus 90 and get 510 cm.
