Answer:
I had this question on a quiz. I got it wrong and when I looked back at it, it told me this was the correct answer...
Step-by-step explanation:
b= 2A over h minus a
or b= (2A)/h -a
Sorry if this was not helpful, this one confused me too
A= 5
B= 3
A= 5 +5+5+5= 20
B= 3 (length) x 3 (width)
The answer to the first question is 7.15
The answer to the second question is 1.73
