A triangle has a side length of 4 centimeters and an area of 12 square centimeters. A similar triangle has a corresponding side length of 16 centimeters. Find the area of the larger triangle. A 64 cm^2
B 108 cm^2
C 256 cm^2
D 192 cm^2

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

what shape is

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
