Write a simplified expression using exponents that represents the area of the square.
olganol [36]

Answer:

The area of the square is 25d^{2}.

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

= 25d^{2}

Therefore, the answer is 25d^{2}.
