Answer:

15.8

Step-by-step explanation:

First off, I think you mean area. You can't find the perimeter of a triangle with only two sides listed, neither can you find that side unless you have the perimeter.

1. Area of the triangle formula is axb/2= (9.9x3.2)/2, which when put in a calculator is 15.84.

2. Rounded to 1DP makes it 15.8
