Answer:
Perimeter = 63.9 cm.
Area = 166.96 cm^2 to the nearest hundredth.
Explanation:
The perimeter = 16+20.9+27 = 63.9 cm.
To find the area you can use Heron's Formula.
Area = √ [ s(s-a)(s-b)(s-c)] where s = the semi-perimeter and a, b and c are the lengths of the 3 sides.
s = 63.9 / 2 = 31.95.
Area of the triangle = √ (31.95(31.95-16)(31.95-20.9)(31.95-27)]
= 166.96 cm^2.
