Respuesta :
than you check this quadratic what is area of rectangle so this can being factorized
k^2 +19k +60 = (k+4)(k+15) and we know that area of a rectangle is given by the product of the length and width
so in this way result that bc. area equal (k+4)(k+15) where k+15 mean the length of rectangle so in this way result that k+4 mean the width of rectangle and hence the choice B. is right sure
hope this is understandably sure right easy for you
