Answer:
BFC makes this angle add up to 90 degree at BFD
Therefore it becomes complementary to angle CFD
Answer:
Length of rectangular strip = 12
area of rectangular strip = 2*12 = 24
Area of square = x^2 = 12^2 = 144
Step-by-step explanation:
Area of square x^2
area of rectangle is given by length * width
Length of rectangular strip = x
width of rectangular strip = 2
area of rectangular strip = length * width = 2*x = 2x
Area of square piece of paper when rectangular strip is taken away from it
= Area of square - area of rectangular strip
= 
It is given that Area of square piece of paper when rectangular strip is taken away from it is 120 square units.
Thus,

Thus,
either x+10 = 0 or x -12= 0
x = -10 or x = 12
but length cannot be negative hence neglecting x = -10
hence value of x is 12.
Hence,
Length of rectangular strip = 12
area of rectangular strip = 2*12 = 24
Area of square = x^2 = 12^2 = 144
The interpretation of 0 = -12 is (a) There are no solutions to the system because the equations represent parallel lines.
<h3>How to interpret the result?</h3>
The result is given as:
0 = -12
By comparison 0 and -12 do not have the same value
i.e. 0 ≠ - 12
This means that the system of equation has no solution
Hence, the interpretation of 0 = -12 is (a)
