Answer: 
Step-by-step explanation:
Given
The temperature on Tuesday is 
Temperature drops to 
on Wednesday
Net drop in temperature 
The temperature drops twice from Wednesday to Thursday
Temperature on Thursday
m^2 -11m -60 = 0
m^2 -11m =60
(m^2 -11m + 121/4) = 361/4
(m - 11/2)^2 = 361/4
m - 11/2 = + or - 19/2
m = 11/2 + 19/2, 11/2 - 19/2
m = 15, -4
---------------------------------------------------
m^2 -11m -60
(11 +- Square root (121 +240))/2
11/2 +- 19/2
m= 15, -4
----------------------------------------------------
m^2 -11m -60
(m - 15) (m + 4)
m = 15, -4
The area is the product of length and width, which is to say that the length and width are factors of the area.
Assuming the dimensions are integers, you want factors of 84 that differ by 5.
... 84 = 1×84 = 2×42 = 3×28 = 4×21 = 6×14 = 7×12
The last of these pairs differ by 5, so ...
- the length is 12 inches
- the width is 7 inches.
