Answer:
Step-by-step explanation:
you just gotta add all the side-lengths together and consider each grid square as 10 instead of 1.
so 70 + 40 + 20 + 60 + 20 + 40 i believe.
this all equals 250.
ask your teacher if its a type, because there's no 250 on there. grab a calculator or something as proof.
