Given the formula A = 1/2 (a+b)h, find:
1. a if A = 360, b - 25, h = 16
2. b if A = 252, a = 18, h =12
~~~~~~~~~~~~~~~~~~~



(1)  From  A = , you have


      = a + b,

     a = .


     Substitute given values A, h and b into the formula and calculate "a".




(1)  Similarly, from  A = , you have

      = a + b,

     b = .


     Substitute given values A, h and "a" into the formula and calculate "b".

Happy calculations (!)
