Find the similarity ratio and the ratio of perimeters for two regular octagons with areas of 18in2 and 50in2
sweet-ann [11.9K]

Answer:

3. 3 : 5; 3: 5

Step-by-step explanation:

First, let's find the leght of the sides of each octagon.

A= 18in^{2}

The area of an octagon is defined by

A=2(1+\sqrt{2})l^{2}

Replacing the area

18=2(1+\sqrt{2})l^{2}\\\frac{18}{2(1+\sqrt{2})} =l^{2}\\l=\sqrt{\frac{18}{3.4} } \approx 2.3 \ in

Therefore, the side of the first octagon is 1.6 inches long.

Its perimeter is: P=8(2.3in)=18.4in

A=50 in^{2}

50=2(1+\sqrt{2})l^{2}\\\frac{50}{2(1+\sqrt{2})} =l^{2}\\l=\sqrt{\frac{50}{3.4} } \approx 3.8 \ in

Therefore, the side of the second octagon is 3.8 inches long.

Its perimeter is P=8(3.8in)=30.4in.

Now, let's divide to find each ratio:

\frac{3.8}{2.3} \approx 1.65 (the ratio between sides).

\frac{30.4}{18.4} \approx 1.65 (the ratio between perimeters).

Therefore, the closest ratio is 3. 3 : 5; 3: 5

Q is an even number so that choice B can't be answers because 3 is an odd number .

and for A 6 isnot a prime number so that it proves tim is correct.

but when we see D 2 is a prime number so that it shows tim is wrong.
