First we find the scale factor. It went from a 11 cm length to 16.5 cm length....so we have to find out what to multiply 11 by to get 16.5.
11x = 16.5
x = 16.5 / 11
x = 1.5
and since we multiplied 11 * 1.5 = 16.5, then we have a scale factor of 1.5...so we now multiply the height of 4 by 1.5.
So the new height is gonna be : 4 * 1.5 = 6 cm <==

notka56 [123]

Answer: y=3

Step-by-step explanation:

Since the quadrilateral has 90 degree angles, it must be a a square or a rectangle. This means the measure of sides left and right are the same and the measure of sides top and bottom are the same.

To get the measure of y, you can use left and right or top nd bottom.

I'll use left and right. 10=2y+4 => 10-4=2y => 6=2y => y=3

You can check it by substituting. 2(3)+4=10      The answer is the measure of the right side, which is the same as the measure of the left side.

I hope this helps you!
