Shape length/base width/height square 0.8 ft. 0.8 ft. rectangle 0.65 ft. 0.5 ft. triangle 0.6 ft. 0.6 ft.
if someone erased two of the triangles and added two squares, what
would the new area of the hopscotch course be if the squares’ sides
measured 0.9 feet? after finding the new area, add the shapes to the
picture to show what the new course might look like.

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?

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.
