Answer:

The area of rectangle URST is 135 mm² ⇒ 3rd answer

Step-by-step explanation:

- Congruent rectangles have same lengths of sides, same measures

 of angles and same areas and same perimeters

- Rectangle ABCD is congruent to rectangle URST

- The length of sides A B is 9 millimeters and the length of sides R S is

  15 millimeters

- We need to find the area of rectangle URST

∵ Rectangle ABCD ≅ rectangle URST

∴ AB = UR , BC = RS , CD = ST , AD = UT

∵ AB = 9 millimeters

∴ UR = 9 millimeters

- The area of any rectangle = l × w, where l, w are its dimensions

- In rectangle URST

∵ UR = 9 millimeters

∵ RS = 15 millimeters

- Assume that UR = l and RS = w

∴ The area of rectangle URST = UR × RS

∴ The area of rectangle URST = 9 × 15 = 135 millimeters²

* <em>The area of rectangle URST is 135 mm²</em>
