Answer: 30
Step-by-step explanation:
If we were to draw diagonal BD, then we would create two congruent triangles, and we could find the area of each using the formula
.
However, since there are two triangles, we can double this, giving us
.
So, the area is 
Approximatley 4.39. If thought of like .33X=1.45, then you just divide 1.45 by .33
Answer:
h= −15 /2
Subtract 6h from both sides.
