1. Find the area and perimeter of the triangle.

16 cm

27 cm

Perimeter = 63.9 cm.

Area = 166.96 cm^2 to the nearest hundredth.

Step-by-step 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.
