Answer:
⇝Formula Used :-
✧ Area of rectangle :
{\large{\red{\bigstar \: \: {\blue{\underbrace{\underline{\orange{\bf{Area = Length \times Breadth }}}}}}}}}★
Area=Length×Breadth

⇝Solution :-
❒ Area of tiles :
✧ Area of tiles :
{\large{:{\longmapsto{\bf{Area = Length \times Breadth}}}}}:⟼Area=Length×Breadth
\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: {\large{:{\longmapsto{\bf{12 \times 5}}}}}:⟼12×5
\: \: \: {\large{\red{\dashrightarrow}} \: \: {\underline{\underline{\orange{\bf{60 {cm}^{2} }}}}}}⇢
60cm

❒ 1st Case :
✧ Area of rectangular region :
{\large{:{\longmapsto{\bf{Area = Length \times Breadth}}}}}:⟼Area=Length×Breadth
\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: {\large{:{\longmapsto{\bf{70 \times 36}}}}}:⟼70×36
\: \: \: {\large{\red{\dashrightarrow}} \: \: {\underline{\underline{\orange{\bf{2520 cm}}}}}}⇢
2520cm
✧ Tiles required :
{\large{:{\longmapsto{\bf{2520 \div 60}}}}}:⟼2520÷60
{\large{\purple{:{\longmapsto{\underline{\overline{\boxed{\bf{42 \: tiles}}}}}}}}}:⟼
42tiles
❒ 2nd Case :
✧ Area of rectangular region :
{\large{:{\longmapsto{\bf{Area = Length \times Breadth}}}}}:⟼Area=Length×Breadth
\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: {\large{:{\longmapsto{\bf{144 \times 100}}}}}:⟼144×100
\: \: \: {\large{\red{\dashrightarrow}} \: \: {\underline{\underline{\orange{\bf{14400 \: cm}}}}}}⇢
14400cm
✧ Tiles Required :
{\large{:{\longmapsto{\bf{14400 \div 60}}}}}:⟼14400÷60
{\large{\purple{:{\longmapsto{\underline{\overline{\boxed{\bf{240 \: tiles}}}}}}}}}:⟼
240tiles
❒ Hence :
{\large{\green{1.}{\underline{\pink{\pmb{\underline{\mathfrak{ \: 42 Tiles}}}}}}}}1.
