Answer:
A
Step-by-step explanation:
The rectangle has an area of 30ft^2
Each triangle has an area of 25ft^2
25+25+30=80
For this case we have that by definition, the Greatest Common Factor or GFC of two or more numbers, is the largest number that divides them without leaving residue.
So:
We look for the factors of 18 and 36:
18: 1,2,3,6,9,18
36: 1, 2,3,4, 6,9,18 ...
Thus, the GFC of both numbers is 18.
Then, the GFC of
and
is:
