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.
A.3 yd
B.4 yd
C.5 yd
D.6 yd
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.
