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
To find the length of the missing side, we can use the fact that the perimeter of a quadrilateral is equal to the sum of all its side lengths.
Let's calculate the perimeter by adding up the given side lengths:
6 yd + 4 yd + 4 yd + 6 yd + blank yd = 25 yd
Now, let's simplify the equation:
20 yd + blank yd = 25 yd
To find the value of blank yd, we can subtract 20 yd from both sides of the equation:
blank yd = 25 yd - 20 yd
Simplifying further, we have:
blank yd = 5 yd
Therefore, the length of the missing side is 5 yd.
The correct answer is option C. 5 yd.
