Calculate the area of parallelogram.

the answer is 61

Step-by-step explanation:

if you multiply 12x2 it is 24, 11.5x2 is 23, 7x2 is 14 add that all together and the answer is 61.

The correct answer is:  [B]:

   "The square of the hypotenuse is equal to the sum of the squares of the legs."

Note:  Hence the formula / equation for the Pythagorean theorem for a right triangle:

        a² + b² = c²  ;  

in which "c" is the length of the hypotenuse of a right triangle; 
& in which "a" and  "b" are the lengths of the other two sides of the right triangle.
