Carolyn determines that the area of a shaded triangle is half the area of a shaded triangle because the ratio of the side lengths of a white triangle to a shaded triangle is 3/6. Is Carolyn correct? Explain

Area=1/2 times base times height

lets say base and height=3 for one triangle and

base and height=6 for another

area1=1/2 times 3 times 3=9/2

area2=1/2 tmes 6 times 6=18

areas are

9/2 to 18=9:36=1:4

3:6=1:2

is 1:2=1:4? no

ratio is 1:4
