cm,
please solution. ​

Answer 1

Answer:

area of triangle formula is 1/2 × base× hieght

Step-by-step explanation:

4(a). =1/2×4×42

= 84 sq cm

4(b). = 1/2× 5.6× 7.5

=1/2× 31.30

= 31.30/2 sq cm

Answer 2

Step-by-step explanation:

A)

h=4 3/4 cm = 19/4 cm

b= 4 cm

area of triangle=( 1/2)× b×h

=( 1/2)× 4× 19/4

= 19/2= 9.5 sq cm

B)

h=7.5cm

b= 5.6 cm

area of triangle=( 1/2)× b×h

=( 1/2)×5.6× 7.5

= 21 sq cm
