Answer: Length = 42ft Width = 21ft
Step-by-step explanation:
Let "w" be width
W = 21ft
w x 2 = L
L = 42ft
Perimeter:
42+42+21+21
=126

Option C
The distance of a spin of one full rotation is 31.4 feet
<em><u>Solution:</u></em>
Given that,
A circular merry-go-round has a radius of 5 feet
Radius = 5 feet
We have to find the distance of spin for one full rotation
Distance covered in 1 full of rotation is equal to circumference of circle
<em><u>The circumference of circle is given as:</u></em>

Where "r" is the radius

Thus the distance of a spin of one full rotation is 31.4 feet
