The equation for area of a triangle is given below.
Area of Triangle = 0.5*Base*Height
Since we are given that the base is 8 yards and height is 3 yards...
Area of Triangle = 0.5 * 8 yards * 3 yards = 12 yards^2
Answer:

2. a subtracted by one or a minus one or one less than a
3. x divided by two subtracted by four or x seperated by two minus four or four less than x partitioned by two
4. five y added to nine or five y plus 9 or 9 more than five y
Answer:
18432 km/h
Step-by-step explanation:
It is given that a sound wave travels through iron at a rate of 5120 m/s.
We know that
1 km = 1000 m
1 hour = 60 minutes
1 minutes = 60 second
Using these conversions we get
1 m = 0.001 km
1 hour = 3600 second


Therefore, the sound wave travels through iron at a rate of 18432 km/h.
