Answer:
1682
Step-by-step explanation:
2120 grams of sand in bucket - 438 grams of sand in cup = 1682 :)
|AD|=(3i-1j)-(-3i-0j)=3i-1j+3i+0j=6i-1j
|BA|=(-3i-0j)-(-1i+3j)=-3i-0j+1i-3j=-2i-3j
Area =|AD|x|BA|
= i j k
6 -1 0
-2 -3 0
= -1 0 i - 6 0 j + 6 -1 k
-3 0 -2 0 -2 -3
= 0 i - 0 j + (-18-2)k = -20 k
√(-20)² =20
