Answer:

a) Length = 7.2 cm

b) Perimeter = 17.2 cm

c) Area = 12 cm²

Step-by-step explanation:

From pythogras theorem;

${ \rm{l = \sqrt{ {4}^(2) + {6}^(2) } }} \\ \\ { \rm{l = √(16 + 36) }} \\ \\ { \rm{l = √( 52) = 7.2} \: cm}$

Perimeter

${ \tt{ = 6 + 4 + 7.2}} \\ = { \tt{17.2 \: cm}}$

Area:

${ \tt{area = (1)/(2) * base * height }} \\ \\ { \tt{area = (1)/(2) * 6 * 4}} \\ \\ { \tt{area = 3 * 4}} \\ \\ { \tt{area = 12 \: {cm}^(2) }}$
