please answer this question ​

Answer 1

Answer:

120

Step-by-step explanation:

bc it is an equilateral tria

Answer 2

Option D

Area= √3/4 x a^2

Whera a is equal to side length

So area of bigger triangle of 10cm length

√3/4 x (10)^2

And area of smaller triangle of side 1cm

√3/4x(1)^2

So the ratio of

Smaller triangle: larger triangle

100:1

So 100 smaller triangles(side1cm) will be made in the larger triangle (side 10cm)
