Calculate the speed of a car if it covers the distance of 100m in 5seconds.​

20m per seconds

Step-by-step explanation:

Speed= Distance/Time

= 100/5

= 20

20m/s

Step-by-step explanation:

Distance(d)=100m

Time taken(t)=5 seconds

Speed(v)=?

We know that,

v=d/t

=100/5

=20m/s

Therefore,Speed(v)=20m/s

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .

x=25tan30=14.43 or the answer is b
