## Question number: 123

### Write in Short

The image shows Indian Flag.

(a) Given that length of Indian Flag is 1.5 times more than that of width, if width of flag is 60 cm, find length of the Indian flag.

(b) If ratio of width and length of flag is 2: 3, if length is 900 mm, find width of the flag.

### Explanation

Here,

(a) Length of Indian Flag is 1.5 times more than that of width and width of flag is 60 cm.

So, 2 times means, but here 1.5 times means.

So, length will be 90 cm.

(b) Here, ratio of width and length of flag is 2: 3.

Length is 900 mm. Let’s take width = w.

So, ratio will be: .

## Question number: 125

### Write in Short

The points A and B are marked on the diagram.

(a) Write as a column vector.

(b) . Write down the co-ordinates of C.

### Explanation

Here, as shown in figure,

(a) Here, Point A = (2,3) and point B = (3, -4)

So, for vector of , so as a column vector:

(b) Here, , so as a row vector we can write as (-5, -2), let take co-ordinate of C = (x, y) and B (3, -4) is given.

So,

So, C (x, y) = **C (-2, -6) **
