I need help with this. Thanks.

Write a program in assemble to calculate the area of a trapezoid of the following parameters.

- shorter side a=3,

- longer side b=7,

- height h=4.

result= (a+b)/2 x h

the whole code is not required. Just show how you would declare all variables that you would need to calculate the area of trapezoid (a, b, h).
