Answer:
length = 20 mt
Width = 16 mt
Step-by-step explanation:
Let the length of the field be x
width of the field be y
Hence formula of the perimeter is given as
P=2(x+y)
P=72(given)
72=2(x+y)
Dividing both sides by 2 we get
x+y=36---(A)
Also given that width of the parallelogram is 4 meters less than its length
Hence
y=x-4
or x-y=4 ---(B)
Adding A and B
2x=40
x=20
y=x-4
y=20-4=16
Hence length = 20 mt
Width = 16 mt
30 min = 30/60 hr = 0.5 hr
d = rt
100 = r*0.5
100/0.5 = r
200 = r
r = 200 mph.
We know that Rate = distance/time
(30 minutes is .5 hour)
Rate=100 mile/.5 hour
Divide and we get:
Rate=200 MPH
(Hint: MPH is Miles per Hour---Per means "for each")
Make sense?
