Which quadrilateral with side lengths shown will have a perimeter of 20 meters? 6 m, 5 m, 4 m, 6 m 7 m, 4 m, 4 m, 6 m 3 m, 7 m, 3 m, 7 m 6 m, 3 m, 5 m, 5 m next

  3 m, 7 m, 3 m, 7 m

Step-by-step explanation:

The perimeter is the sum of the side lengths, so the perimeters of your quadrilaterals are ...

6 m + 5 m + 4 m + 6 m = 21 m . . . . ≠ 20 m

7 m + 4 m + 4 m + 6 m = 21 m . . . . ≠ 20 m

3 m + 7 m + 3 m + 7 m = 20 m . . . . . This is it!

6 m + 3 m + 5 m + 5 m = 19 m . . . . ≠ 20 m

2/4 is the answer

step-by-step explanation:

x= total pieces

both ate 9 pieces

mindy ate 3 so troy ate 6

6= (1/4)x

x =24
