Answer:
38 cm^2
Step-by-step explanation:
The surface area of a rectangular prism is
SA = 2(lw+wh+lh) where h is the height l is the length and w is the width
SA = 2( 3*1 + 3*4+4*1)
= 2(3+12+4)
= 2(19)
= 38 cm^2
Probably the property of subtraction.
-TTL
The perimeter is the total of the length • 2, + Width • 2. Doing it in reverse order, 230 - 2(Width) = 104.
104/2 = 52
