Answer 2

Answer: Rs 75

Step-by-step explanation:

Cost of carpet = Rs. 160

Side of square room = 8 m

Area of square room = a² = 8²= 64 m²

Cost per m² is $= \dfrac{Total cost}{area} = \dfrac{160}{64} =Rs. 2.5$

Area of rectangular room $= l\tikes b = 6\times 5 = 30 m^2$

Cost of carpet for rectangular room = 30 x 2.5= Rs. 75

Hence, the cost of carpet is Rs. 75
