Question

what is the perimeter of a quadrilateral whose four sides measure 3whole 1/6 cm, 2whole 3/4 cm, 4whole 5/12 cm, and 2whole 1/2 cm.​

Answer 1

Step-by-step explanation:

Perimeter of quadrilateral = Sum of all sides

$= 3\frac{1}{6} + 2 \frac{3}{4} + 4 \frac{5}{12} + 2 \frac{1}{2} \\ = \frac{19}{6} + \frac{11}{4} + \frac{53}{12} + \frac{5}{2} \\ = \frac{19 \times 2}{6 \times 2} + \frac{11 \times 3}{4 \times 3} + \frac{53}{12} + \frac{5 \times 6}{2 \times 6} \\ = \frac{38}{12} + \frac{33}{12} + \frac{53}{12} + \frac{30}{12} \\ = \frac{38 + 33 + 53 + 30}{12} \\ = \frac{154}{12} = \frac{77}{6}$
