Question

Please help me answer the question. Thank you very much

Answer 1

So since these are similar all you need to do is creat a ratio for each rectangle.
X/20 is the first rectangle and 6/14 is second. Whichever edge you put on top for the first, you also need to for the second.
Now set them equal to each other and cross multiply.
X 6
__ = __

20 14

14x= 120

Now divide by 14 on both sides
14x= 120
__ ___

14 14

X=14/120

Now finally simplify. I’m dividing by two since it goes into both.
7/60 would then be your answer

Answer 2

X/6= 20/14
You have to move six to the other side and multiply, it by the fraction so that your equation becomes
x=6*20/14
Which is
8.57
