Question

What is the area of Square B in the figure below?

Answer 1

STEP 1:

Find the length of the square B

In the image above, the length of square B is "b".

$\begin{gathered} \text{But, b}^2=9 \\ b=\sqrt[]{9} \\ b=3 \end{gathered}$

STEP 2:

Find the area of the square B

$\begin{gathered} \text{Area of a square = length x length} \\ \text{Area of square B= b x b} \\ =3\text{ x3} \\ =9 \end{gathered}$
