the area of the base of a rectangular desk telephone is 754 square centimeters. the length of the rectangular telephone is 3 centimeters longer than its width.
(a) what are the length and width, in centimeters, of the desk telephone?
(b) what are the length and width, in millimeters, of the desk telephone

Area is found by multiplying the length by the width.

Let X = width.

The length is x +3 ( 3 cm longer than the width).

Now you have area = x * x+3

Area is given as 754 square cm.

754 = x * x+3

Simplify:

754 = x^2 +3x

Subtract 754 from both sides:

x^2 +3x - 754 = 0

Factor:

(x -26) (x+29)

Solve for x:

x = 26 and -29.

Since the dimension cannot be negative, x = 26.

The width = 26 cm.

The length = 26 +3 = 29 cm.

Multiply each dimension by 100 to get millimeters:

Width = 260 mm

Length = 290 mm

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
