I’m not sure how to describe it but it seems like x will always go +1 and y will always go 1 higher than the last. So 1,1 = x +1, y +2. 2,3 = x +1, y +3.
Answer: 1.25 square feet
This converts to the improper fraction 5/4
===========================================================
Explanation:
The area of the triangle on the left is base*height/2 = 0.5*2/2 = 0.5 square feet. Note that 1/2 = 0.5
The area of the triangle on the right side is base*height/2 = 0.2*3/2 = 0.75 square feet. This converts to the fraction 3/4
Add up the two results: 0.5+0.75 = 1.25 square feet
-----------
If you need the answer as an improper fraction, then,
1.25 = 1 + 0.25
1.25 = 1 + 1/4
1.25 = 4/4 + 1/4
1.25 = (4+1)/4
1.25 = 5/4
