Area of room is=13×9=117m. Length of required carpet X metre. Area of carpet=x×75=75x metre

Step-by-step explanation:

Answer 2

$\sf{\bold{\green{\underline{\underline{Given}}}}}$

• Length of room = 13m
• Breadth of room = 9m
• Width of carpet = 65cm = 0.65m
• Cost of carpeting 1 m = Rs. 64

$\sf{\bold{\green{\underline{\underline{To\:Find}}}}}$

• Cost of carpeting the room = ??

$\sf{\bold{\green{\underline{\underline{Solution}}}}}$

$\sf{\red{\boxed{\bold{Area = Length\times Breadth}}}}$

⠀⠀⠀⠀

Area of the room = 13 × 9

⠀⠀⠀⠀

Area of the room = 117m²

⠀⠀⠀⠀

Area of the room = Area of the carpet

⠀⠀⠀⠀

Therefore;

⠀⠀⠀⠀

Area of the carpet = 117 m²

⠀⠀⠀⠀

$\sf{\red{\boxed{\bold{area = length \times breadth}}}}$

⠀⠀⠀⠀

117 = 0.65 x length

⠀⠀⠀⠀

length = 117 / 0.65

⠀⠀⠀⠀

length = 11700 / 65

⠀⠀⠀⠀

length = 2340 / 13

⠀⠀⠀⠀

length = 180 m

⠀⠀⠀⠀

Now ;

⠀⠀⠀⠀

Cost of 1 m of carpet = Rs. 65

⠀⠀⠀⠀

Cost of 180m of carpet = 180 × 65

⠀⠀⠀⠀

Cost of 180 m of carpet = Rs. 11700
