Answer
The perimeter is $32.45$ meters and the area is $48$ m$^{2}$.
Work Step by Step
1. Find the perimeter of the triangle by adding the sides up
Let $P = $ the perimeter of the triangle
$P = 11.8 + 8.65 + 12$
$P = 32.45$ m
2. Find the area of the triangle
Let $A =$ the area of the triangle
$A =( base \times height) \div 2$
$A = (12 \times 8) \div 2$
$A = 96 \div 2$
$A = 48$ m$^{2}$
