Answer:
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!
