Find the area of the shape shown below

42.5

Step-by-step explanation:

9 x 3.5 = 31.5

2 x 2 = 4

2 x 2 / 2 = 2

2 x 5 / 2 = 5

31.5 + 4 + 2 + 5 = 42.5

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

47 - 90 = 43

43 - 180 = x

x = 137
