The perimeter of any quadrilateral is the sum of all its sides.
So,
6 yd + 4 yd + 4 yd + 6 yd + x yd = 25 yd
20 yd + x yd = 25 yd
x yd = 25 yd - 20 yd
x yd = 5 yd
Therefore, the missing side length is 5 yd.
The answer is option C.
Which is the length of the missing side?
A quadrilateral is shown with side lengths of 6 yd, 4 yd, 4 yd, 6 yd and blank yd. The perimeter is given as 25 yd.
