• GIVEN:-
Dimension of tiles is 5cm and 12cm
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
• To Find:-
Number of tiles needed to fit in region of
100cm and 144cm
70cm and 36cm
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
• Solution:-
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
1.)
Given that,
Length of the tiles = 5cm
Length of the tiles = 5cmBreadth of the tiles = 12cm
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
\mathrm{Therefore,}Therefore,
\large\underline{\boxed{\bf\green{Area = length \times breadth}}}Area=length×breadth
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
➪ \sf Area = 12 \times 5Area=12×5Area=12×5Area=12×5
★ \bf\red{Area = 60 \: cm^2}Area=60cm2
Also,
Length of the rectangular region = 100cm
Length of the rectangular region = 100cmBreadth of the rectangular region = 144cm
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
\mathrm{Therefore,}Therefore,
\large\underline{\boxed{\bf\green{Area = length \times breadth}}}Area=length×breadth
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
➪ \sf Area = 100 \times 144Area=100×144Area=100×144Area=100×144
★ \bf\red{Area = 14400 \: cm^2}Area=14400cm2
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
\mathrm{Hence,}Hence,
The tiles required to fit in the given region will be,
No. of tiles = Area of the region / Area of the one tile
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
➪ \sf No. \: of \: tiles = \dfrac{14400}{60}No.oftiles=6014400
★ \large{\bf\pink{No. \: of \: tiles = 240 \: tiles}}No.oftiles=240tiles
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
2.)
Length of the rectangular region = 70cm
Length of the rectangular region = 70cmBreadth of the rectangular region = 36cm
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
\large\underline{\boxed{\bf\green{Area = length \times breadth}}}Area=length×breadth
➪ \sf Area = 70 \times 36Area=70×36Area=70×36Area=70×36
