Help find the answer for a and b worth 10 points

a) 2a + 6(a - 2) = 44

b) short side = 7 cm     long side = 15 cm

Step-by-step explanation:

a)    (2 x a) + [2 x 3(a - 2)] = 44

      2a + 6(a - 2) = 44

b)    2a + 6(a - 2) = 44

       2a + 6a - 12 = 44

           8a -12 = 44

              8a = 56

                a = 7

       Therefore, one side has length of 7 cm, and the other has

       length of 3(7 - 2) = 15 cm.

Hope this helps!
