Given :-

✧ How many tiles whose length and Breadth are 12cm and 5cm respectively will be needed to cover a rectangular region whose length and breadth are :

1. 70cm and 36cm

2.144cm and 1m

Formula Used :-

Area of rectangle :

{\large{\red{\bigstar \:  \: {\blue{\underbrace{\underline{\orange{\bf{Area = Length  \times Breadth  }}}}}}}}}

▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃

Solution :-

Area of tiles :

✧ Area of tiles :

{\large{:{\longmapsto{\bf{Area = Length  \times Breadth}}}}}

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: {\large{:{\longmapsto{\bf{12 \times 5}}}}}

 \:  \:  \: {\large{\red{\dashrightarrow}} \:  \: {\underline{\underline{\orange{\bf{60  {cm}^{2} }}}}}}

1st Case :

✧ Area of rectangular region :

{\large{:{\longmapsto{\bf{Area = Length  \times Breadth}}}}}

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: {\large{:{\longmapsto{\bf{70 \times 36}}}}}

 \:  \:  \: {\large{\red{\dashrightarrow}} \:  \: {\underline{\underline{\orange{\bf{2520 cm}}}}}}

✧ Tiles required :

{\large{:{\longmapsto{\bf{2520   \div 60}}}}}

{\large{\purple{:{\longmapsto{\underline{\overline{\boxed{\bf{42  \: tiles}}}}}}}}}

2nd Case :

✧ Area of rectangular region :

{\large{:{\longmapsto{\bf{Area = Length  \times Breadth}}}}}

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: {\large{:{\longmapsto{\bf{144 \times 100}}}}}

 \:  \:  \: {\large{\red{\dashrightarrow}} \:  \: {\underline{\underline{\orange{\bf{14400 \:  cm}}}}}}

✧ Tiles Required :

{\large{:{\longmapsto{\bf{14400  \div 60}}}}}

{\large{\purple{:{\longmapsto{\underline{\overline{\boxed{\bf{240  \: tiles}}}}}}}}}

Hence :

{\large{\green{1.}{\underline{\pink{\pmb{\underline{\mathfrak{  \: 42 Tiles}}}}}}}}

{\large{\green{2.}{\underline{\pink{\pmb{\underline{\mathfrak{  \: 240 \:  Tiles}}}}}}}}

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
