Question

Find the lateral area of each prism. Round to the nearest tenth if necessary.

The dimension labeled 11 is the height of the prism.

Question 4 options:

334 units2

264 units2

299 units2

312 units2

Answer 1

264 unit^2.

Explanation:

The lateral area is the sum of the 2 sides of area 5*11 and the 2 sides of area 7^11.

That would be 2 * 5 * 11 + 2*7*11

= 264 unit^2.

Answer 2

For this case we have that by definition, the lateral area of a prism is given by:

`LA = 2ac + 2bc`

Where:

a: It is the height

b: It is the width

c: It's the long

According to the figure we have:

`a = 5 \ units\\b = 7 \ units\\c = 11 \ units`

Substituting:

`LA = 2 * 5 * 11 + 2 * 7 * 11\\LA = 110 + 154\\LA = 264`

Finally, the lateral area of the prism is
`264 \ units ^ 2`
