Find the perimeter of the original triangle?

Answer 4

i dont understand dilated

Answer 5

To dilate means to scale up, if you dilate by 3
then each side will be 3 times of the original side
\[7\longrightarrow 7 \times 3=21\]
Now you find all the sides and then find perimeter, then compare new perimeter with the original perimeter
