Answer:


(c) 4 small squares
Step-by-step explanation:
Given
<u>Small Square:</u>

<u>Large Square:</u>
i.e. twice as long as the small square
Solving (a): The area of the small square.
This is calculated as

So, we have:

Solving (b): The area of the large square.
This is calculated as

So, we have:


Solving (c): Number of small square to cover the large square
To do this, we simply divide their areas.
Let n represents the required number; n is calculated as:



<em>Hence, 4 small squares is required to cover the large square</em>
Multiply 5 and 9 which is 45.
