Any ideas?

no

skullpatrol · Answer

Do you know what a "scale drawing" is?

anonymous · Answer

no im afraid i dont

Let's start there.

hello?

skullpatrol · Answer

Hi.

anonymous · Answer

sorry there was something wrong with my internet connection.

skullpatrol · Answer

np

anonymous · Answer

Don't we have the height of the hall?

anonymous · Answer

so i draw a scale drawing of the following measurements.. then?

anonymous · Answer

50m long and 30m wide

skullpatrol · Answer

As the question states: "use your scale drawing to find the actual distance "

skullpatrol · Answer

So that means you would measure it off the diagram.

anonymous · Answer

no thats not what it means

anonymous · Answer

but thanku.

anonymous · Answer

Yeah,but that gives you only 2 out of the 3 dimensions of the hall. To draw the 3D diagram,we would need the height

skullpatrol · Answer

@najda  What does it mean to you?

skullpatrol · Answer

@AishwaryaHB  strictly speaking the "opposite" corner is from the ground to the roof, but since we are not given the height we are left with a two dimensional "opposite".

anonymous · Answer

In that case,your answer would be 58.3m,or something around that value

skullpatrol · Answer

But the question asks to use the scale drawing.

skullpatrol · Answer

make a scale drawing of a rectangular school hall which is 50 m long and 30 m wide using a scale of 1 cm to 5 m, use your scale drawing to find the actual distance between the opposite corners of the hall.

anonymous · Answer

yeah,so make 1!
according to the scale given,1cm=50 m.
so,in the drawing,your length would be=50/5=10cm and your width would be=30/5=6cm.
It's a rectangular hall,so draw a rectangle with length 10cm and width 6cm.
The length of the diagonal of this rectangle will represent the distance between any 2 opposite corners of the hall.

anonymous · Answer

The length of the diagonal is ~11.6cm
since 1cm=5m,
11.6cm=5*11.6m
=58m
