19. Types of Agricultural Inputs
•Consumable Inputs- frequently used
agricultural inputs for smallholder
farmers, usually natural materials
that will be consumed naturally by
the crops such as high-quality seeds,
soil, fertilizer, insecticide, insect traps,
straw, water, and others.
20. Capital Inputs – agricultural inputs
that are often mechanical and
more technologically advanced
and cannot be consumed by the
crops themselves such as nylon
setting, stakes, tractors, plows,
irrigation system, and others .
21. Shape/Figure Formula Illustrative Example
Triangle
h- height
B- base
Area = ½
(Base X
Height
A = ½(bxh)
A piece of land
is triangular,
find the area of
the land if the
base is 10m
and the height
is 15m.
22. Solutions:
•Base = 10m
•Height =15m
•A = ½(b x h)
•A = ½ (10m x 15m)
•A = ½ (150m 2)
•A – 75m 2
•Answer:
•A – 75m2
•The surface area of the triangular farmland is
seventyfive square meters.
23. Shape/figure Formula Illustrative Example
Rectangle
W=
width
L= length
Area =
Length x
Width
A = l x w
A rectangular
land has 200
meters in
length and 100
meters width,
what is its area?
25. Shapes/ Figures Formula Illustrative Example
Square
S=Side
Area =
square
unit of
sides
A = s2
What is the surface area of
the lettuce field that has a
side of 100 meters?
A= 100m x 100m
A=10,000 m 2
The surface area of the
lettuce field is
10,000 m2
26. Solution
• A = s2
A= 100m x 100m
Answer
A=10,000 m 2
The surface area of the lettuce field is
10,000 m2
27. Exercises:
1. A piece of
land is a
triangular
shape. Find
the area if the
base is 5m and
the height is
10m.
2. What is the
surface area of
of the rice field
