Answer
$$6.59 \ m, \ 1.86\ m^2. $$
Work Step by Step
Recall the Pythagorean theorem
$$c^2=a^2+b^2$$
First, we use the Pythagorean theorem to find the hypotenuse; that is
$$c= \sqrt{2.04^2+1.82^2}=2.73 \ m.$$
The perimeter of a triangle is the sum of its sides; that is,
$$Perimeter=2.04+1.82+2.73=6.59 \ m. $$
The area of a triangle is half of the base times the corresponding height; that is,
$$Area=\frac{1}{2} \times 2.04 \times1.82=1.86\ m^2. $$
