Sam is outlining his pool with tiles. Each tile is t inches long. He used 50 tiles along the width of the pool. The length of his pool is ten inches less than twice the width. Write an expression for the length of the pool, and use it to help you write a simplified expression for the Area of the pool in square inches. Draw a picture to help organize your work.

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
