If x = 12 units, y = 3 units, and h = 14 units, find the area of the parallelogram shown above using decomposition.
1 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 traignel=1/2bh
aera=1/2(10)(3)
area=5(3)
area=15
rectangel of legnth x and height h
area=legnth timwe width
x=8
h=10
area=8 times 10
aera=80
last triangle
should
add
15+80+15=120
