1. 1st and 3rd side: 1^2+1^2=a^2, a^2=2, a=root2      2nd and 4th side: 3^2+3^2=b^2, b^2=18, b=3*root2area of rectangle is: a= 2*a+2*b, a=2*root2+2*3*root2, a=8*root2=11.3137088498984762. 1st side: a=4      2nd sode: b^2=1^2+3^2, b^2=10, b=root10      3rd side: c^2=5^2+3^2, c^2=34, c=root34a=root(s(s-a)*(s-b)*(s- s=(a+b+c)\2, s=(4+root10+root34)\2, s=6.496614778, s-a=2.496614778, s-b=3.334337118, s-c=0.6656628832a=7.3991277883. 1st side: a=8      2nd and 5th side: b=7      3rd and 4th side: c^2=4^2+5^2, c^2=32, c=root32, c=4*root2we can split this perimeter into rectangle of area 2*a+2*b=30, and triangle of area (a*4)/2=16.a=30+16=46
