Answer 1

Answer:

40 cm

Step-by-step explanation:

ratio is 3:5 so that means there are (3+5) = 8 parts in total

since the perimeter is 64 cm we do 84/8 to fin how much 1 part of it is = 8

now just fill in the ratio with the real numbers

3 * 8 = 24

5 * 8 = 40

so the length is 40 cm

Answer 2

Answer:

Length of rectangle is 12cm.
