Answer:

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

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

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!
