How do I find the surface area of this shape?

235.2 inches

Step-by-step explanation:

bottom triangle:

base = 12 in

height = 10.4 in

area = (1/2) (12 × 10.4) = 62.4

side triangles:

base = 12 in

height = 9.6 in

area = (1/2) (12 × 9.6) = 57.6

Surface Area:

3(57.6) + 62.4 =

172.8 + 62.4 = 235.2

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
