Question

6. You must fill the wall in the foyer with square-shaped signages. The wall is 2 m high and 2 m wide. Calculate how many squares you will be able to put up if each sign is 40 cm long and 400 mm wide.

​

Answer 1

Step-by-step explanation:

number of squares = area of wall/ area of one sign

both in mm

2000 x 2000 / 400 x 400

5 x 5 = 25

Answer 2

Given,

The height of the wall$\[ = 2{\rm{000mm}}\]$

The width of the wall$\[ = 2{\rm{000mm}}\]$

The length of the square$\[ = 4{\rm{00mm}}\]$

The width of the square$\[ = 4{\rm{00mm}}\]$

Solution,

Formula used, the area of a square$\[ = {\rm{Lenght}} \times {\rm{Breadth}}\]$

Therefore, the number of squares is

$\[\begin{array}{l} = \frac{{2000 \times 2000}}{{400 \times 400}}\\ = \frac{{20 \times 20}}{{4 \times 4}}\\ = \frac{{400}}{{16}}\\ = 25\end{array}\]$

Hence, the number of the squares are $\[25.\]$
