Question

FIRST GETS BRAINLLEST If the triangle below is enlarged by a scale factor of 2, what will be the perimeter of the new triangle? 16 units 19 units 21 units 24 units

Answer 1

Answer: 21 units

There are two ways to do this. The first method you would multiply each original side by 2 to get 7 for each side. The new perimeter would be 7+7+7 = 21.

Or you could find the perimeter of the original figure (3.5+3.5+3.5 = 10.5) and then multiply that by 2 to get the same result (10.5*2 = 21)
