Answer:
a)
length of bedroom =x m
Breadth of bedroom =5 m
And, length of kitchen =15−(x+2)=13−x m
Breadth of kitchen =5 m
So, Area of both kitchen and bedrooms =2× times of area of bedroom + area of kitchen
=2(5×x)+(13−x)×5
=10x+(65−5x)
=(65+5x)m2
(b)
From figure,
Perimeter of the living room
=15+2+x+5+(15−x)+5+2=44m
(c)
From figure,
Total area of both living the room and the bedrooms =(5×x)+(7×15)=(5x+105)m2
The cost of carpeting is Rs. 50/m2
Therefore, total cost of carpeting
=(5x+105)×50=Rs.250(x+21)
(d)
Total area, bathroom and kitchen
=(15−x)×5m2
The cost of tiling is Rs. 30/m2
Therefore, total cost of tilling
=(15−x)×5×30=Rs.150(15−x)
(e)
Given, Area of floor of each bedroom 35 m2
So, Area of one bedroom
=5xSq.m
∴5x=35
⇒x=7m
