If a 12 meter tall airplane hangar casts a 18 meter shadow at the same time parked jet casts a 6 meter shadow, how tall is the jet?

The answer is 5 meters tall is the measurement of a parked jet.

Step-by-step explanation:

 12 meters tall airplane

 18 meter shadow of airplane

 6 meter shadow of jet

Find the measurement of the jet (y)

Solution

6y = 12 + 18                         30

       >     y   =    >  y= 5

6           6                              6

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
