Fill in the gap using 1 to 9 to give a result close to 0
First, you have to determine what kind of numbers that are close to 0;
In this case, I'll work with -0.4 to 0.4 because the number in this range approximate to 0;
Next, is to fill in the gaps using trial by error method

Answer:
A
Step-by-step explanation:
The area (A) of a triangle is calculated using the formula
A =
bh ( b is the base and h the perpendicular height )
here b = 14 and h = 4, hence
A =
(14 × 4) = 28
