One of Julian's friends also has a rectangular aquarium. The dimensions of his friend's tank are each exactly 1 1/4 times the di
daser333 [38]

Answer:

468.75 square inches

Step-by-step explanation:

Let the length of Julian's tank be x

Let the width of Julian's tank be y

So, Area of Julian's tank=Length \times Width =xy

Since we are given that Julian's tank is approximately 300 square inches

So, xy=300  --1

Now we are given that  The dimensions of his friend's tank are each exactly1\frac{1}{4} =\frac{5}{4}times the dimensions of Julian's tank.

So,length of his friend's tank =\frac{5}{4}x

So,width of his friend's tank =\frac{5}{4}y

So, Area of his friend's tank=\frac{5}{4}x \times \frac{5}{4}y

                                             =\frac{25}{16}xy

                                             =\frac{25}{16}(300) (Using 1)

                                             =468.75

Hence the approximate area of the rectangular base of his friend's tank is 468.75 square inches.

So, Option D is correct.
