15m : 40m = 35m : 65m

Answer:

False.

Consider the two ratios 15m : 40m = 35m : 65m

15/40 = 35/65

15/40 is further simplified by dividing both numerator and denominator by 5 we get,

= 3/7

35/65 is further simplified by dividing both numerator and denominator by 5 we get,

= 7/13

Hence, 3/7 ≠ 7/13

Therefore, 15/40 ≠ 35/65

"hello students welcome to lido q a video
session i am saf
your math tutor and question for today
is
praveen wanted to make a temporary
shelter for her car
by making a box like structure with the
carpal in
that covers all the four sides in the
top of the car
with the front face as a flap which can
be rolled up
assuming that the stitching margins are
very small
and therefore negligible how many dart
power lines
would be required to make the shelter of
the height
2.5 meter with base dimensions
4 meter into 3 meter
so here first of all length breadth and
height we have to
make clear so length breadth and height
of the shelter is given to be length is
if 4 meter
breadth is 3 meter and height is 2.5
meter that is clear from the question
now tarpaulin will be required for the
top and the four wall side of the center
so using the formula the area of the
tarpaulin required will be written as
we can write area formula here as 2
into length into height
plus breadth into height
plus length into breath as
it is covering the top we have
length into height
and four side walls that is length into
height plus breadth into height
so that is how formula is designed now
let us put the values of
length breadth and height
so area will be equal to 2 into 4 into
2.5
plus 3 into
2.5 and outside it there is length into
height
that is 4 into 3.
and that will be equal to 47
we can write one more step here that is
2
into 10 plus
7.5 plus
12 meter square
so it will be equal to 47
meter square therefore
47 meters square we can write here
powerpoint can be required
and that is our final answer that 47
meter square area
of the tarpaulin will be required to
cover roof
and the side walls so
