Question

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

Answer 1

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
