2D-a^2=2

2(a√2) -a^2=2

a^2-2√2*a+2=0

2a= 2√2 + √(8-4*2) = 2√2
hence, perimeter = 4a = 2*2a=2*2√2 = 4√2

1 coin is 4 ways
2 coins is 4*3 ways
3 coins is 4*3*2 ways
4 coins is 4*3*2*1 ways

so total is 4+12+24+24=64 sums

$\\ \sf\longmapsto -4x+13y=7$

$\\ \sf\longmapsto 13y=4x+7$

$\\ \sf\longmapsto y=\dfrac{4x+7}{13}$

$\\ \sf\longmapsto y=\dfrac{4}{13}x+\dfrac{7}{13}$
