Help

Step-by-step explanation:

Rectangle:

length = 12 cm ; width = 6cm

Area = lenght*width = 12*6 =  72 cm²

Triangle A:

base = 3cm

height = 6cm

= 9 cm²

Triangle B:

base = 3cm

height = 6cm

=9 cm²

d) Parallelogram:

base = ( 12 -3) = 9 cm

Height = 6 cm

Area = base * height = 9*6 = 54 cm²

or u can also find as mentioned dowm

Area of parallellogram = Area of rectanle - (Area of Triangle A + Area of triangle B)

= 72 - (9+9) = 72 - 18 = 54 cm²

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
