The perimeter of quadrilateral ABCD will be 26 units.
It should be noted that we want to measure the length of each side of ABC, and use those lengths to calculate the perimeter of ABC.
This will be 10, 5, 5, and 6. Therefore the perimeter will be the addition. This will be:
= 10 + 5 + 5 + 6
= 26 units.
This also was identical to the result gotten. This is attached below.
