Question 1177544


The area of the base of a rectangular desk telephone is 864 square centimeters.

 The length of the rectangular telephone is 5 centimeters longer than its width.

let width be w
length = w+5
w(w+5) =864
w^2+5w-864=0
(w + 32)(w - 27)=0

taking positive value w=27

​ the length is 32 and width =27 cm.
​ the length is 320 mm and​ width is 270 mm
