# A computer manufacturing company would like to come up with a new laptop computer such that its monitor is 80 square inches smaller than the present ones.suppose the length of the monitor of the larger computer is 5 inches longer than its width and the area of the smaller computer is 70 square inches.what are the dimensions of the monitor of the larger computer?

Let width of larger monitor be W

Then length of larger monitor = W + 5

Area of larger monitor = W(W + 5), or W^2+5W

Since area of smaller monitor is 70 sq”, and since this area is 80 sq” smaller

than the larger monitor, then area of larger monitor = 150 (70 + 80) sq"

Now, we can say that: W^2+5W=150 ------ W^2+5W-150=0

(W - 10)(W + 15) = 0

Width of larger monitor, or W = 10 inches W = - 15 (ignore)

Length
Let width of larger monitor = W
Then length of larger monitor = W + 5
Area of larger monitor = W(W + 5), or W^2+5W
Since area of smaller monitor is 70 sq”, and since this area is 80 sq” smaller
than the larger monitor, then area of larger monitor = 150 (70 + 80) sq"
Now, we can say that: W^2+5W=150 ------ W^2+5W-150=0
(W - 10)(W + 15) = 0
Width of larger monitor, or W = 10 inches W = - 15 (ignore)
Length of larger monitor: 10 + 5 = 15 inches

Asmall = 70

Alarge = Asmall +80
= 70 + 80
= 150 in²

Let x be the width
x+5 =  length

A = (length)(width)
150 = (x+5)(x)
150 = x² + 5x
0 = x² +5x - 150
0 = (x+15) (x-10)
x=-15 ; x=10        [Use x=10 because we can not have a negative dimension]

Width = 10 in
Length = 15 in      [width + 5]
wow tnx now i understand the problem
