In both cases, the area of the triangle can be computed from the formula
  A = (1/2)bh
where b is the length of the base, and h is the height perpendicular to the base.

1. It is convenient to use DE as the base. Its length is 4-1 = 3. Then the height is the distance from F to DE, which is 1-(-3) = 4. By the formula, the area is
  A = (1/2)(3)(4) = 6

2. It is convenient to use LK for the base. Its length is 4-0 = 4. Then the height is the distance from J to the line y=-5, which is -1-(-5) = 4. By the formula, the area is
  A = (1/2)(4)(4) = 8

Add digit by digit, from the right, just like any number, except that if it adds to 2, then put a zero and carry one (instead of carrying when it adds to 10 or more).

Example:  < means carry, decimal equivalent for checking
1011+1111

     1     0     1     1         (8+2+1=11)
+   1     1     1     1         (8+4+2+1=15)
---<---<----<----<----
1   1     0     1     0         (16+8+2=26)

Proceeding similarly,
a. 10101111+11011011 = 110001010  (394)
b. 10010111+11111111  = 110010110  (406)
c.  01110101+10101100 = 10010001  (289)
