An insect crawls around rectangular plates for 1 time = 30 + 20 = 50cm
It means it covers 50cm distance at first round.
when it travels 10 times on rectangular plate = 50 × 10 = 500cm = 5 meter
Total distance traveled by it is 500cm or 5 m.

Step-by-step explanation:
Length of the rectangular plate = 30 cm
Breadth of the rectangular plate = 20 cm
Perimeter = 2(l+b)
= 2(30+20)
= 2×50
= 100 cm
Now,
Total distance travelled by insect = 10 times perimeter.
So,
Total distance travelled = 10×100
= 1000 cm
= 10 m
