As you were copying the question, did you notice the drawing alongside it ?
Well, see, that sketch is actually part of the question; anybody who wants to
try and answer it needs to see that drawing.
If the perimeter is 84 feet and the length is twice the width, then the length will be 28 feet and the width will be 14 feet.
This is missing some information. For instance, it does not say what 84 is. Is it the radius, the circumference? See the link below for a step by step guide to finding a diameter.
14 feet (14+14+28+28 = 84)
Area = Length * Width = 12*7 = 84 square inches.
It is 14 times 6 = 84 square cm
(14/84) x 360° = 60°
84*r*pi/180 units of length where the radius is r units of length.
Circumference equals pi times diameter; so C = 84*pi or about 263.9.
For any circle . . .Diameter = circumference/pi .
A circumference of 263.89 cm
circumference = 84*pi
84 units x 3.1416 = 264 units (approx)
7 foot circumference X 12 inches/foot = 84 inches in circumference
it is 3,897,769,560.5647393748 ft around the earth According to WGS-84, IAU 1976 and 2000, the exact length of the equator to the nearest whole number is 24,901 miles, or 40075 kilometers.
The circumference is approximately 527.79 units. The formula is: C = 2*Pi*r
