Question 1189582
.
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
~~~~~~~~~~~~~~~~~~~


<pre>


(1)  From  A = {{{(1/2)*(a+b)*h}}}, you have


     {{{(2A/h)}}} = a + b,

     a = {{{(2A)/h-b}}}.


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




(1)  Similarly, from  A = {{{(1/2)*(a+b)*h}}}, you have

     {{{(2A/h)}}} = a + b,

     b = {{{(2A)/h-a}}}.


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

Happy calculations (!)
