Area: 20 x 30 so 600
perimeter: 20 + 20 + 30 + 30 = 100
The answer is 20cm
Multiply the width and the hight then divid by twi
In order to find the volume of a triangular pyramid, you must use the formula (abh)/6. Therefore, I believe the answer is 12 (if [a = a] [b = h] and [c = b]).

If you take the amount of green markers and divide them by the total, you come up with 0.21
If you do likewise with the others, you respectively come up with 0.47 and 0.32.
