Pls help I’ll give crown

This shape is just a rectagle with triangles ontop.

Lets work out the rectangle first. 12 x 9 = 108.

Now the triangles.  The area for traingle is 1/2 base x height so 2 x 12 = 24 / 2 = 12. So each triangle is 12 ft ^2. You have 2 so it is 24.

24 + 108 =132 ft^2

keep ur crown

50- 250 is correct i did that one too

step-by-step explanation:

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
