Answer:
≈44.44%
Step-by-step explanation:
≈44.44%
To solve this, we can use a simple proportion.
Assuming 18 = 100%...

Then, using cross multiplication...


Now divide 18 from both sides.
x ≈ 144.44
Now subtract 100 from ≈144.44, leaving us with
≈44.44%
45-5 =40
40/2 = 20
20+5 = 25
the 2 numbers are 20 and 25
So attached is the plotting of the triangle and I estimated it's area to be 7 squared units
(OPTION C).
Note: in the graph i used colour codes to represent those partial squares that I used to counted as one and the gray squares are the naturally whole ones.
Hope this helps
