Length = √area = √81 = 9
diagonal = √2 * side = √2*9 = 9√2
19 if u add all separately but it is 89 it u don't
Answer:
g-21
Step-by-step explanation:
First you would want to add all of the hours traveled already. Since g would be the total amount of house that Greg would need to drive to get to his destination you would subtract the amount of hours traveled from g. 8+9+4=21, 21 hours traveled already. The expression would be g-21.
Use the Pythagoras' Theorem:
A^2 + B^2 = C^2
20^2 + 35^2 = C^2
400+ 1225=1625=C^2
square root of 1625= C = 40.31 km
