Answer: a=17 mm length
b=37 mm width
Step-by-step explanation:
P=2a+2b
a -length
b-width
b=2a+3
------------------
108mm=2a+2(2a+3)
108=6a+6
6a=102
a=17 mm
b=17*2+3
b=34+3
b=37 mm
The number -5 is anything but natural number.
It is an integer (Z) ,a rational number (Q) and a real number (R) .
X=26
Because 90-38=52
52/2=26
A squared + b squared = c squared
