Answer 1

$A_{losango} = \frac{D.d}{2} \\ \\ A_{paralelogramo} = \frac{b.h}{2} \\ \\ \\ D=2.3x=6x \\ \\ d=2.2x=4x \\ \\ A_{losango} = \frac{6x.4x}{2} = \frac{24x^2}{2} =12x^2 \\ \\ A_{paralelogramo} = \frac{(x+5)2x}{2} = x(x+5) =x^2+5x \\ \\ \\ A_{losango} = A_{paralelogramo} \\ \\ 12x^2=x^2+5x \\ \\ 12x^2-x^2-5x=0 \\ \\ 11x^2-5x=0 \\ \\ x(11x-5)=0 \\ \\ x=0 \\ \\ 11x-5=0 \\ \\ 11x=5 \\ \\ x= \frac{5}{11}$
