Based on the given coordinates, the perimeter of the quadrilateral is 22.62 units.
<h3>What is the perimeter?</h3>
To find the perimeter, you need to find the distance between each point on the shape as this will show the sides of the shape.
The distance between two points is found as:
= √ ( (x₂ - x₁) + (y₂ - y₁))
Using this formula, the distance between QR is 7.07.
The distance between RR is 4.24.
The distance between RT is 7.07
The distance between QT is 4.24
The perimeter is therefore:
= (2 x 7.07) + (2 x 4.24)
= 22.62 units
