Answer:
c is less than or equal to -17
Step-by-step explanation: -19 +2
The area of a trapezium side is (5 + 13) /2 * 6 = 54cm2. So the area of both trapezium sides is 108cm2.
The four rectangle sides all have the same width, so they have an area of 3 * (9 + 5 + 8 + 13) = 105cm2.
So the total surface area of the figure is 213cm2!
No pair of 'real' numbers can do that.
The numbers are 'complex'.
They
are
0.5 + 1.936i
and
0.5 - 1.936i .
The symbol ' i ' stands for the
square root of -1 .
