# Chapter 8 - Geometry - 8.5 Triangles - 8.5 Exercises - Page 564: 5

Area of the Triangle = $A$ = 139.15 cm$^{2}$ Perimeter of the Triangle = $P$ = 58.9 cm

#### Work Step by Step

Area of a Triangle: $A$ = $\frac{1}{2}$$b$$h$ Therefore: $A$ =$\frac{1}{2}$(25.3 cm)(11 cm) $A$ = 139.15 cm$^{2}$ Perimeter of a Triangle: $P$ = $a$ + $b$ + $c$ Therefore: $P$ = 25.3 cm + 18 cm + 15.6 cm $P$ = 58.9 cm
