1. Input:1, output:4
2. Input:1, output:6
3. Input:5, output:8
3. Input:5, output:10
The different between the inputs and outputs are 3, 5, 3, 5. See the pattern?
Hope this helped.
longer congruent sides = 6-0 OR 4-(-2) = 6units
perimeter= 3.6×2 + 6×2 = 19.2units
height of parallelogram= 2-(-1) = 3 units
area= 3×6 = 18unit^2
