Question

Rectangle ABCD ~ Rectangle WXYZ. Find the missing measurement

Answer 1

Answer: 14

Explanation:

Since they are similar, that means their side lengths are proportional.

Therefore,
`(WX)/(AB) = (WZ)/(AD)`.

We can plug in the values we know:

Let x be the missing measurement.

`(16)/(24) =(x)/(21)`

We can simplify 16/24 to 2/3.

2/3 = x/21.

We can cross multiply:

42 = 3x

Therefore, x = 14
