Veronika [31]

111.2

Step-by-step explanation:

As per the question, 15 times 15 i.e. 225

15 \times 15 = 225

225 divide by 20 i.e. 11.25

\frac{225}{20}  = 11.25

take away five from the 11.25 then it will be 11.2

Add 100 to 11.2 i.e

11.2 + 100 = 111.2

Mario is constructing a square dart board. It will consist of a smaller square centered in a larger square. The smaller square m
Ivan

Answer:

6 inches.

Step-by-step explanation:

Let a represent side length of larger square.

We know that area of square is square of its side length, so area of the larger square will be a^2.

The area of smaller square would be 4^2.

We will use proportions to solve our given problem.

\frac{\text{Area of smaller square}}{\text{Area of larger square}}=\frac{4}{9}

\frac{4^2}{a^2}=\frac{4}{9}

\frac{16}{a^2}=\frac{4}{9}

Cross multiply:

4*a^2=16*9

\frac{4*a^2}{4}=\frac{16*9}{4}

a^2=36

Take square root:

a=\pm\sqrt{36}

a=\pm 6

Since the length cannot be negative, therefore, the side length of larger square is 6 inches.
