Answer : 27 triangles
Explanation : Considering if one triangle has 1/18 [tex] m^{2} [/tex] area
n triangle have n x 1/18 [tex] m^{2} [/tex]
To composed an area of 3/2 [tex] m^{2} [/tex] we need to get 27 triangles each having an area of 1/18 [tex] m^{2} [/tex]
Since 27 ×1/18 [tex] m^{2} [/tex]
= 3/2 [tex] m^{2} [/tex]
