an engineer is to design a rectangular computer screen with a 19-inch diagonal and a 175-square inch area. find the dimensions of the screen to the nearest tenth of an inch
solution
let length is x and width is y
diagonal square root of (x^2+y^2)=19
x^2+y^2=361
xy=175
(x+y)^2=361+350=711 THAN X+Y=26.66
(X-Y)^2=361-350=11 THAN X-Y=3.31 BY SOLVING BOTH EQUATION WE WILL GET X=14.988 INCHES
Y=11.678 INCHES
