I’m struggling to answer this question on my test, can someone explain it to me?

Correct answer is Option A: 18/48 = 21/56

You’ll have to divide the numerator by the denominator of each fraction to see whether they have the same quotient:

18/48 = 0.375
21/56 = 0.375

The other options are not proportional.

B) 20/28 = 15/18:

20/28 = 0.714
15/18 = 0.833

Thus, 20/28 ≠ 15/18

C). 3/5 = 13/10
3/5 = 0.6
13/10 = 1.3

Hence, 3/5 ≠ 13/10

D) 7/10 = 10/7
7/10 = 0.7
10/7 = 1.43

Thus, 7/10 ≠ 10/7

These solutions prove that the correct answer is A) 18/48 = 21/56

area = 12 units²

Step-by-step explanation:

The perimeter of a plane figure is the distance around it.

The triangle has sides that measure 2 units, 5 units, and 5.39 units. It means that the perimeter of the rectangle would be

2 + 5 + 5.39 = 12.39 units

The circumference of a circle is the same as its perimeter.

Perimeter of circle = 2πr

Where

r represents the radius of the circle.

π is a constant whose radius is 3.14

If the circumference of the circle and the perimeter of the triangle is the same, then

2 × 3.14 × r = 12.39

6.28r = 12.39

r = 12.39/6.28

r = 1.97

Area of circle = πr²

Therefore,

Area of circle = 3.14 × 1.97² =

12 units²
