Calculate the perimeter for the parallelogram if a= 7.6 , b= 5.9 and c= 14.6

kolezko [41]

Although the problem gives the value of b, it's really not needed.

Opposite sides of a parallelogram are congruent, so we just need to calculate: 2a + 2c = P

Plug the given values in:

2 * 7.6 + 2 * 14.6 = 44.4 units, or choice (C).
