"hello students welcome to lido q a video
session
i am sef your math tutor and question
for today is
the length breadth and the height of the
room are 5 meter
4 meter and 3 meter respectively find
the cost of
whitewashing the walls of the room and
the ceiling
at the rate of rupees 7.50 per meter
square
length of the room is given that is l
5 meter breadth of the room b
is 4 meter
and height of the room h is 3 meter
it can be observed that the four walls
and the ceiling room
are to be white washed so
total area to be whitewashed will be
equal to total area of the wall
plus area of the ceiling of the room
and that will be equal to 2 into length
into height
plus breadth into height
plus
length into breadth so this is how we
find the sum of two areas
area of the wall is two into length into
height plus breadth into height
bracket plus area of ceiling that is
length into breath
now we will substitute substitute each
of this value 2
into bracket of length into height that
is
5 into 3 plus breadth into
height that is 4 into 3
plus land into breath 5
to 4 so it will give you
30 plus 24
plus 20
and that is 74
so 74 meter square is our
area also
we can find the cost of whitewash per
meter square
that is cost of whitewash
we can find cost of white was for the
whole area
it is given that the cost of whitewash
per meter square
is given in the question that is 7.50
rupees
so cost of whitewash
for whole area
will be equal to
so here cost will be equal to
7.50 into obtained area
that is 74
and that is equal to rupees
555 hence
finally we have found the area total
area to be white was and after total
area we have found
we have found the cost of white wall for
the whole area
so cost of
whitewash is rupees
555 555. if you have any query
