Answer:
Where is the diagram though..
Step-by-step explanation:
Multiply 40.5 by 800
you get 32400
then divide by 100 to get to meters
324 meters
rounding to nearest 10 to any number follow these rules
1. if number ends 0 , 1 , 2 ,3 4 , 5 take number down to nearset multiple of 10
2. if number ends with above 5 take the upper number multiple of 10
so here
413 + 35.6 + 998.5 + 376 + 85.3
= 410 + 40 + 1000+ 380 + 90
= 1920
