Question

What is the perimeter of a parallelogram if the shorter side of the parallelogram is 5.4cm and the longer side is half as much again as the shorter side?

Answer 1

Answer:

$b = 5.4cm\\l = 5.4 + \frac{5.4}{2}\\l = 5.4 + 2.7\\l = 8.1cm\\\\perimeter = 2(l + b)\\perimeter = 2(5.4 + 8.1)\\perimeter = 2(13.5)\\perimeter = 27cm$
