Question

A rectangular sheet of paper measurs 60m by 40m. use a scale of 1cm to 10m and make a scale drawing of the sheet of paper .
Hence find the length of a diagonal of the sheet of paper
​

Answer 1

Answer:

Well... simply use the formula that in a right-angled triangle...

a

2

+

b

2

=

c

2

Distribute the rectangle sheet of paper into two triangles like this..

Now... let

60

=

a

40

=

b

Then....

60

2

+

40

2

=

c

2

If you're thinking that it's a very big number and how will you multiply it... notice that there's a zero in the end so it's just like this

60

2

=

3600

as

6

2

=

36

and you added two zero's as there is one in the square root

Solve

3600

+

1600

=

c

2

5200

=

c

2

It is not a perfect square but notice that it's between

72

2

=

5184

and

73

2

=

5329

But as it is more close to the

72

2

one... it is almost

72

c

m
