A room is half as long again as it is broad. The cost of carpeting the at Rs. 5 per sq.m is Rs. 270 and the cost of papering the four walls at Rs. 10 per m2 is Rs. 1720. If a door and 2 windows occupy 8 sq. m, find the dimensions of the room. Choose the correct answer
A) 6,18,6	B) 6,18,0	C) 6,18,7	D) 6,18,2	E) 6,18,1
Explanation:   Let breadth = x metres, length = 3x metres, height = H metres.   Area of the floor=(Total cost of carpeting)/(Rate) = (270/5)=

<output>54</output>
54   So, breadth= 6 m and length = = 9 m.   Now, papered area = (1720/10)= 
<gadget id="calculator">(1720/10)</gadget>
<output>172</output>
172   6,18,6rea of 1 door and 2 windows= 8   Total area of 4 walls = (172 + 8)= 
<gadget id="calculator">(172 + 8)</gadget>
<output>180</output>
180   6,18,6nswer: 6,18,6) b=6;l=18;H=6
