Question

10. Damarion is finding measurements from the triangular prism shown.

a. Damarion finds the perimeter of the base to be 48 units.

Explain his error.


b. Damarion finds the area of the base to be 96 units2.

Explain his error

Answer 1

The answer is "32 and 48"

Explanation:

Please find the graph file in the attached file.

The perimeter is= sum of sides

`= 10+10+12 \\\\ =32 \ units\\\\`

Calculating the Area of base
`= (1)/(2) * base * height`

`= (1)/(2) * 12 * 8\\\\= (1)/(2) * 96\\\\=48 \ units^2`
