Question

PLEASE ANSWER THIS QUESTION

Answer 1

The answer is 36, because when you divide 80/20 it is going to be 4 and 9*4 is 36!

Answer 2

Answer:

w = 36 inches

Step-by-step explanation:

Since the two rectangles are similar, the ratios of their height is equal to the ratio of their widths.

Therefore, you can make an equation such that:

$\frac{width_1}{width_2} = \frac{height_1}{height_2}$

width 1 = 9 inches

width 2 = w inches

height 1 = 20 inches

height 2 = 80 inches

Plug into the ratio equation:

$\frac{9}{w} =\frac{20}{80}$

$\frac{9}{w}=\frac{20 * 1}{20 * 4}= \frac{1}{4}$

$\frac{9}{w} =\frac{1}{4}$

$9 * 4 = 1 * w$

w = 9 * 4 = 36 inches
