please I need help

Step-by-step explanation:

volume=area *lenght

for area=2area of triangle +area of rectangle

a=2root(s(s-a)(s-b)(s-c))+7*4    {s is  (a+b+c)/2    so  s=(3+4+5)/2  finding 5 by pythagoras theorem    so s=6}

a=2root(6(6-2)(6-4)(6-5))+28

a=2root48+28=41.85inch^2

now  volume=41.86*5  given in fig height is 5

so v=209 inch^3

2nd one in the first row is correct
