We need the length of the sides.
AB=√(2-(-2))²+(4-1)²=√16+9=√25=5; BC=√4²+0=4; CA=√0+9=3. AB+BC+CA=5+4+3=12.

Answer:

Surface area of the rectangular prism= $168 yards^2$

Step-by-step explanation:

Given Dimensions of the rectangular prism are:

$Length(L)= 9 yards\\\\Width(w)=2 yards \\\\Height(H)= 6 yards$

Surface Area of a rectangular prism=

$2(L*W+W*H+H*L)\\\\ =2(9*2+2*6+6*9)\\\\ =2(18+12+54)\\\\ = 2(84)\\\\$

= $168 yards^2$

The surface area of the rectangular prism is $168 yards^2$
