Answer» From I and II. Length `=3x=48m` `therefore x=16` Breadth `=2x=32m` Hence, Area of floor `=48xx32` Cost of flooring `=48xx32xx850=Rs. 1305600` From I and III, `2(1+b)=160` `implies2(3x+2x)=160implies10x=160` `therefore x=16` `therefore "Length"=3xx16=48m` Breadth `=2xx16=32m` Cost of flooring `=(48xx32)xx850=Rs. 1305600` Similarly, from II and III, we can find I = 48 m and b =32m and Total cost of flooring = Rs. 1305600 |
