essie is helping her grandmother plant a garden in the shape of the trapezoid shown. ​ ​ ​ The garden will have the following dimensions: • base one is feet long • base two is times the length of base one • height is feet What is the area, in square feet, of this garden?

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

noncoplanar points are points that do not lie on the same line.
