Estimation and Basic

Calculation
Estimation
 Estimation is an important concept for farmers. Much
of farming is unpredictable, due to weather reliance
and grain markets. Farmers try to estimate the yield of
a certain field of grain. To do this, farmers pick a plant
and count how many seeds are on the head.
 It also a method of measurement and forecasting
whereby analysts or farmers predict or estimate the
potential tonnage of a particular crop.

 When calculating how much irrigation water should be
given to a certain field, the size of the field must be known.
Common areas
 In mathematics, you learned that areas can be
calculated and measured.
 It is important to be able to measure and calculate
areas of traingle, square, reactangle, trapezoid, and
parallelogram rather than just doing an estimation.
 There are agricultural farm owners who are
knowledgeable with their farm area, while others are
not.
 Farm owners have lands that are regular or irregular
shape.
 Majority of farm decisions depend upon the accuracy
Calculation of
Areas
Triangle
 The
area of a traingle is calculated
using the formula:
 Tringle = 0.5 × base × height
Squares and
Triangles
 Thearea of a square and rectangle
is calculated using the formulas:
 Square = side × side
 Rectangle = length × width
Parallelogram
Anarea of a parallelogram is
calculated using the formula:
Parallelogram = base × height
Trapezoid
 The
area of a trapezoid is
calculated using the formula:
 Trapezoid
= 0.5 × (base¹ +
base²) × height
Circle
The surface area of a
circle is calculated using
the formula:
Circle = π × r²
That‘s All!!
