The area of the floor in a storage unit is advertised as 171 square feet, Brett calls the facility and is told that the length of the unit is 10 feet longer than its width. Which of the following one of the two dimensions of the unit? a. 3 FT
b. 4 FT
c. 19 FT
d. 23 FT

C. 19 ft

Step-by-step explanation:

Let

Width = x

Length = x + 10

Area = 171 ft²

Area of the floor = length × width

171 = x + 10 * x

171 = x² + 10x

x² + 10x - 171 = 0

Solve the quadratic equation using factorization method

Factors are 19x and -9x

x² + 19x - 9x - 171 = 0

x(x + 19) -9(x + 19) = 0

(x + 19) (x - 9) = 0

x = -19 or x = 9

The value of x can not be negative

Therefore, x = 9 ft

Width = x

= 9 ft

Length = x + 10

= 9 + 10

= 19 ft

options

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
