*CoUgH cOuGh* I need help :D

U STOLE MY PHRASE!!

Step-by-step explanation:

the answer is D

both the triangle have the same with and hight, so it you put them together they would make a square, so when you multiply the length and hight, and you dont have to by  2 then you add all the areas of the squares and rectangles

A

Step-by-step explanation:

A=2(wl+hl+hw)=2·(3·4+3·4+3·3)=60

And to help you more to find the answers to these questions follow these steps.

volume = 0.5 * b * h * length , where b is the length of the base of the triangle, h is the height of the triangle and length is prism length.

area = length * (a + b + c) + (2 * base_area) , where a, b, c are sides of the triangle and base_area is the triangular base area.
