Answer:
the length of side A is 2 cm
Step-by-step explanation:
Hello
you can solve this by using a rule of three
According to the graph, the trapezoid must be proportional ,it means it is possible do the relationships and isolate the data we don't know
if
3 cm ⇒16.5 centimeters
Acm? ⇒11 centimeters
[tex]\frac{3}{16.5}= \frac{A}{11}\\ isolating\ A\\A= \frac{3*11}{16.5} \\A=\frac{33}{16.5}\\ A=2[/tex]
the length of side A is 2 cm
you can use the other length to prove
if
3 cm ⇒13.5 centimeters
Acm? ⇒9 centimeters
[tex]\frac{3}{13.5}= \frac{A}{9}\\ isolating\ A\\A= \frac{3*9}{13.5} \\A=\frac{33}{16.5}\\ A=2[/tex]
I hope it helps,Have a fantastic day.
