svp [43]

Answer:

$Xs=30cm$ and $As=900 cm^{2}$

Step-by-step explanation:

At=As+Ar; A=b.h and $At=4500 cm^{2}$ , then: At=(x+120)x so

(x+120)x=4500, $x^{2} +120x-4500=0$ Applying cuadratic equation formula: $\frac{120+-\sqrt{120^{2} -4.1.-4500} }{2} =-\frac{120+-\sqrt{14400+18000} }{2}= x1=30 and x2=-150, finally Xs=30cm, and As=900cm^{2}$
