A room is twice as long as it is wide. The cost of carpeting it's floor at Rs5.40 per sq.m is Rs 1080 and that of painting it's salt at Rs 1 per sq.m is Rs 630. Find the dimensions of the room
Answers
Step-by-step explanation:
breadth be x
length be x+x/2=3x/2
area of carpeting = cost of carpeting/rate of carpeting
l×b = 270/5
x×3/2x = 54
x^2 = 54×2/3
x^2=108/3=36
x =√36
x= 6
length = 3/2×6=9m
breadth=6m
area of papering = total cost /rate
1720/10=172m^2
total area of papering=172+8 =180m^2
now height =?
2(l+b)×h=180
9+6×h=90
h=90/15
h=6m
hence dimensions of room are 9,6,6 m
