Question

Fill in the blank: The new area is ________ of the original area.

Answer 1

Answer:

one-third

Step-by-step explanation:

As soon as we cut the original triangle into one-third of the triangle. The new area is one-third of the original area

Answer 2

original area :

base= a

height=b

normal area= 1/2ab

change in size

s=a/3+a/3+a/3/2

=3a/3/2=a/2

change in area= 1/2×a/3×a/2

= a²/12
