An equilateral triangle with a base of 20 cm and a height of 17.3 cm is divided into 4 smaller equilateral triangles. What is true about this figure? A. The total perimeter of all 4 triangles is 70 cm. B. The total area of all 4 small triangles is the same as the area of the big triangle, 173 cm2. C. The total perimeter of all 4 triangles is 90 cm. D. The total area of one of the small triangles is 173 cm2.

area scale ratio is 1/4 so every length of a small one is 1/2 the big one's length
the perimeter of the big one is 60
so the perimeter of each small one is 30 and the total is 120, not 70
SO A is FALSE
B is true 10*17.3
C FALSE as shown above
D false obviously 173/4 in fact
