Answer 2

Step-by-step explanation:

Given: Base of triangle =4 cm

Height of triangle =3 × Base of triangle =3×4=12 cm

Area of triangle =21×Base×Height

                           =21×4×12

                           =24 cm2

                           =24×100001 m2[∵1 m=100 cm]

                           =0.0024 m2
