Answer 2

Answer:

164

Step-by-step explanation:

You need to find the area of all sides of the figure.

i first found the front side of the rectangle.

10*4=40 but since there are two of the same shapes, you have to multiply it by two which gives you 80. then you do the same on the top and bottom of the figure.

3*4=12*2=24

10*3=30*2=60

60+24+80=164
