On the grid, draw a quadrilateral that is not a rectangle that has an area of 18 square units. Show how you know that area is 18 square units.

a trapezoid

because the adjacent is 180 so u dived that by 10 that gives u 18 so u divide that be 2 so it's 9 dived by 3 is 3

14

step-by-step explanation:

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.
