Isnt the answer 15? I think so
Answer : 27 triangles
Explanation : Considering if one triangle has 1/18
area
n triangle have n x 1/18 ![m^{2}](https://tex.z-dn.net/?f=%20m%5E%7B2%7D%20)
To composed an area of 3/2
we need to get 27 triangles each having an area of 1/18 ![m^{2}](https://tex.z-dn.net/?f=%20m%5E%7B2%7D%20)
Since 27 ×1/18 ![m^{2}](https://tex.z-dn.net/?f=%20m%5E%7B2%7D%20)
= 3/2 ![m^{2}](https://tex.z-dn.net/?f=%20m%5E%7B2%7D%20)
