What percent of the entire cycle of strokes in an engine is the power stroke to the nearest tenth? Use a 134-degree power stroke. (Remember, it takes two revolutions
to complete the entire cycle.)

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

10 b/c 5*2 =10
