What are the fractions that are at least 9lbs and no more than 16lbs

10 + 6

Step-by-step explanation:

The diagonals of a kite are perpendicular to each other.

Thus the 4 triangles formed are right.

Use Pythagoras' identity to solve for the unknown sides.

UX² = 3² + 9² = 9 + 81 = 90 ( take the square root of both sides )

UX = = = 3

Thus UX = WX = 3

------------------------------------

UV² = 3² + 4² = 9 + 16 = 25 ( take the square root of both sides )

UV = = 5

Thus UV = VW = 5

----------------------------

The perimeter is the sum of all 4 sides, so

perimeter = 5 + 5 + 3 + 3 = 10 + 6 ← exact perimeter
