Solution

Area of carpet $= (15 - 2) (10 - 2) = 13 \times 8 = 104 m^{2}$
Area note covered by the carpet $=$ area of room $-$ area of carpet
$= (15 \times 10) - 104 = 46 m^{2}$

Area of carpet =(15−2)(10−2)=13×8=104m2Area note covered by the carpet = area of room − area of carpet =(15×10)−104=46m2

Area of carpet $= (15 - 2) (10 - 2) = 13 \times 8 = 104 m^{2}$
Area note covered by the carpet $=$ area of room $-$ area of carpet
$= (15 \times 10) - 104 = 46 m^{2}$
