Answer:
800m
Step-by-step explanation:
the sq each side is 100m
the regtanglur lenght - 200 m side - 100 m
so you cancel one hundred from the square and one hundred from the regtanglur
add 200m +100m = 300m
add 200m +100m = 300m
add 300m+ 300m = 600m
add 100m+ 100m = 200m
the just add 600m+200m = 800m
and it done
