Step-by-step explanation:
Hello,
Here in France we call length the greater side of a rectangle.
So:
Let a the greater side
b the shortest
a=b+13
a*b=1764
==>b*(b+13)=1764
==>b²+13b-1764=0
==>b=(-13-85)/2 to exclude
or (b=(-13+85)/2=36 and a=36+13=49)
P=2(a+b)=2(36+49)=170 (m)
Proof:
49-36=13
36*49=1764
