Answer and Step-by-step explanation:
First, write down what we know.
Length of Rectangle = [tex]5\frac{3}{5}[/tex]
Width = [tex]\frac{Length}{2}[/tex]
2 ways to solve this:
1st way:
If we convert the fraction into a decimal, then we can easily find the width.
[tex]5\frac{3}{5}[/tex] can be solved by making the mixed number into a improper fraction.
Multiply the denominator (5) by the whole number (5), then add the numerator (3). This number is 28. Replace the 3 with the 28, and now we have [tex]\frac{28}{5}[/tex]. This number is equal to 5.6.
Now, we have to divide this number.
5.6 divided by 2 is equal to 2.8.
So, the width is equal to 2.8.
Now, we add the width and length together twice to get the perimeter of the rectangle.
2.8 + 2.8 + 5.6 + 5.6 = 16.8
So, the answer is A. 16.8 inches.
2nd way:
Since we know that the width is half of the length, we can just add the length by itself 3 times, since two of the widths combined will equal the length.
5.6 + 5.6 + 5.6 = 16.8
So, the answer is A. 16.8 inches.
