Question

If x = 4 units, y = 12 units, and h = 8 units, find the area of the parallelogram shown above using decomposition.

Answer 1

Yes she is correct all in total you will get the answer of 120

Answer 2

Answer:

if by decomposition you mean breaking it into parts then

break it into 2 triangles and 1 rectangle

left to right

triangle with base y and height h

h=10

y=3

area of triangle=1/2bh

area=1/2(10)(3)

area=5(3)

area=15

rectangle of length x and height h

area= length times width

x=8

h=10

area=8 times 10

aera=80

last triangle

should be same as other since same base (y) and same height (h)

15

add

15+80+15=120
