Answer:
The area of the square is 25[tex]d^{2}[/tex].
Step-by-step explanation:
In the given square, the length of the side = 5d.
Area of a square = side × side
Given: Side = 5d
Now plug in side 5d in the above area formula, we get
Area of the square = 5d × 5d
= 25[tex]d^{2}[/tex]
Therefore, the answer is 25[tex]d^{2}[/tex].
