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>
There’s are ratio which would be 8/10. 12/x should equally 8/10. So it would be 14 tiles long.
Answer:
4
Step-by-step explanation:
Lets make
be the ? in the equation.
That becomes (
x 3) - 3 = 15.
First you have to add 3 on both sides. After doing that it gets to (
x 3) = 15 - 3.
Then you simplify it to 3
= 12.
Now you divide 3 on both sides. That gets to
= 4 after doing it.
