Answer:
When I solve it , I got the answer not the same with you.
( i ) The lateral area of the prism is 204.
( ii ) The total surface area of the prism is 744.
Step-by-step explanation:
( i ) We got that answer because we multiply 17 cm with 12 cm.
( 17 x 12 )
Because it ask only ask for the lateral area which is length and width.
Lateral means side or side so it is length and width not height and
width/length.
( ii ) We got that answer because first step we multiply 17 cm with 12 cm.
We also have to multiply the gotten answer with 2.
Second step, we multiply 12 cm with 7 cm. Almost gonna forgot,
we also have to multiply the gotten answer with 4. Then, add the first
step and second step to make the total surface area.
= ( 17 x 12 x 2 ) + ( 12 x 7 x 4 )
= ( 204 x 2 ) + ( 84 x 4 )
= 408 + 336
= 744
