Question

Find the actual length and breadth of a room which are represented by 6 cm and 4 cm respectively on a scale drawing wih scale of 1 : 200.

Answer 1

here is your answer

Given, length = 6cm

breadth= 4cm

scale=> 1cm= 200cm

Now,actual dimensions=>

Length = 1200cm

breadth = 800cm

Now, area = Length × breadth

=>Area = 1200× 800

=>Area= 96000 cm^2

So area of room is 96000 cm^2 with actual dimensions=>

Length = 1200cm

breadth = 800cm.

Answer 2

$\mathfrak{\huge{Answer:}}$

Given is that:

The length by which the actual length of the room is represented = 6 cm

The breadth by which the actual breadth of the room is represented = 4 cm

The scale given is = 200

That means that 1 cm in the scale represents the actual 200 cm of the room

4 cm will be = 200 × 4

4 cm will be = 800 cm

6 cm will be = 200 × 6

6 cm will be = 1200 cm

Thus, the actual lengths of the room = 800 cm and 1200 cm
