[3](a)A small triangle has area 12 cm². A similar, larger triangle has a length scale factor of 1.5 compared with the small one. Calculate the area of the larger triangle.

[1](a)Two similar shapes have a length scale factor of 2. State the area scale factor.

[2](a)A small triangle has area 15 cm². A similar triangle has a length scale factor of 2 relative to it. Calculate the larger triangle's area.
