I NEED HELPPP ON THIS PLZZZ
Anika [276]

Answer:

Perimeter of ABCD = <u>56 units</u>

Perimeter of WXYZ = <u>140 units</u>

Step-by-step explanation:

<u>To find the perimeter of ABCD, find the sum of all sides</u>

18 + 18 + 10 + 10 = 56

<u>To find the side lengths of WXYZ, use the equation:</u>   \frac{image}{pre-image}

45/18 = 2.5

<em>You can also cross multiply to find the missing side lengths, but I'll show you this other way...</em>

<u>Multiply the pre-image side lengths by 2.5</u>

18 × 2.5 = 45

10 × 2.5 = 25

<em>45 and 25 of the new side length of WXYZ</em>

<em />

<u>To find the perimeter of  WXYZ, find the sum of all sides.</u>

45 + 45 + 25 + 25 = 140

WX = 45, XY = 25, YZ = 45, ZW = 25
