Step-by-step explanation:
To find the area of the triangle:
A=Lenth * Width
A=7*3=21
To find the area of the triangle:
Area=base * height/2
A=7*3/2
7*3=21
21/2=10.5
21+10.5=31.5
Ok so you add it all so it equals 122

40
Step-by-step explanation:
if you used cross products you'd pair 8 with 100 and n with 20
That written out would be 8(100)=20n

800=20n
Divide on both sides
800/20=40
20/20 (cancels out)
Therefore n=40
