$\Large{\underbrace{\sf{\orange{Required\:Solution:}}}}$

Knowledge Required —

★$\large{\boxed{\sf{\orange{Area_{(rectangle)} = Length\times Breadth}}}}$

____________

(b) Areα of this shαpe = Areα of 2 smαll rectαngles + Areα of 1 big rectαngle.

• Substitute the vαlues in the formulαe.

$\longrightarrow{\sf{2(6cm\times 3cm) + 6cm\times (5cm + 3cm)}}$

$\longrightarrow{\sf{2(18cm^{2})+(6cm\times 8cm)}}$

$\longrightarrow{\sf{36cm^{2}+48cm^{2}}}$

$\large\implies{\boxed{\bf{\orange{84cm^{2}}}}}$

(d) Areα of this shαpe = Areα of 2 long rectαngles + Areα of 1 short rectαngle.

• Substitute the values.

$\longrightarrow{\sf{2(4cm\times1cm)+(2cm\times 4cm-1.5cm+1.5cm)}}$

$\longrightarrow{\sf{2(4cm^{2})+(2cm\times1cm)}}$

$\longrightarrow{\sf{8cm^{2}+2cm^{2}}}$

$\large\implies{\boxed{\bf{\orange{10cm^{2}}}}}$
