Question

Here are 2 squares A and B The length of the side of square A is 50% of the length of the side of square B

Answer 1

Answer:

12.5%

Step-by-step explanation:

Although the side of square A is 50% of the side of square B, if you think about things logically here square A is only 25%of square B. Therefore the shaded area HAS to be half of 25% making the answer 12.5%

Hope this helped :)

Answer 2

Answer: 25%

Step-by-step explanation:

Lets start by giving both of the square's lengths a value. So if B's length was 10cm long, and A is 50% of B, then A's length will be 5cm long. Now to workout the area-

Formula to calculate the area of a square= side x side

A= 5 x 5= $25cm^{2}$

B= 10 x 10= $100cm^{2}$

To find the percentage of area A out of B, put the areas in a fraction= $\frac{25}{100}$

You can straight away see that A is 25% of B since the fraction is out of a 100.

Therefore you answer is 25%.
