Answer:
Option (3)
Step-by-step explanation:
Track is shaped as a rectangle with a semicircle on either side.
Therefore, length of the track = 2(Length of rectangle) + perimeter of a complete circle formed by joining the semicircles on each side.
= 2(96) + 2πr
= 
= 192 + 35π
= 192 + 109.9
= 301.9 m
Since, Jake plans to run four laps.
Therefore, distance covered by Jake = 4 × 301.9
= 1207.6 m
Option (3) will be the correct option.
1 foot = 12 inch 20/(5*12) = 20/60 = 1/3 2) .Let x=width 9/5x=length 2W 2L=P 2(x) 2(9/5x)=112 2x (18/5)x = 112 28x = 560 x=560/28 x= 20 inches Width (9/5)x=36 inches Length Check: 2W 2L = P 2(20) 2(36) = 112 8 48 =112
<em>x=3.4</em>
You get this answer by solving for x. First, subtract 4.2 from 5.9 to get 1.7. Then, divide 1.7 by .5 to get 3.4.
