(c) 4 small squares

Step-by-step explanation:

Given

Small Square:

Large Square:

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:

Hence, 4 small squares is required to cover the large square
