Explanation:
a^2+b^2=c^2.
Question A
Each square has a distance of 1, so the bottom is a length of 6, for the sides, they rise 4, and over 3, so 16+9=25, or 5. So the triangle has a perimeter of 16.
Question B
The top has a length of 8 and a bottom length of 5, side BA, (2^2)4+(4^2)16=20, or sqr20, which is 2sqr5 and sqr17 for side DC. So, 5+8+2sqr5+sqr17= 19.5952
