Measurement Formulas
Measurement formulas are the estimation of ratios of quantity it compares a quantity with a standard unit. Measurement formulas are used to find the distance, area, surface area, volume, circumference, etc. They also include some conversion formulas like conversion of an inch to feet, meter to miles, etc. Some of the Measurement Formulas are given below along with a few solved examples, let us see them and learn.
What are Measurement Formulas?
Measurement formulas for the different objects are different. Measurement formulas are very necessary for our calculations of the parameters that we want to know. Measurement formulas for a few objects are expressed below,
Area of a triangle = (1 ⁄ 2) × Base × Height
Distance = \(\sqrt{(x_2x_1)^2(y_2y_1)^2}\)
Area of a Parallelogram = Height × Base
Area of a Rectangle = Length × Breadth
Area of a Square = (side)^{2}
Area of a Trapezoid = \(\dfrac{({base_1+base_2})}{2}\times height\)
Solved Examples Using Measurement Formulas

Example 1: Noah measured the sides of the square to 9 inches, what would be the area of this square? Solve it by using measurement formulas.
Solution:
To find: The area of a square.
The sides of the square = 9 inches (given)
Using Measurement Formulas,
Area of a Square=(side)^{2}
Area of a Square=(9)^{2}^{ }
= 81 m^{2}
Answer: The area of a square is 81 m^{2}.

Example 2: A trapezoidal park that has one base is of length 200 m and the other base is of length 100m also distance between the parallel bases is 50m. what is the area of a trapezoidal park? Solve it by using measurement formulas.
Solution:
To find: The area of a trapezoidal park.
The one base of the park = 200 m
The second base of the park = 100 m
The height of a park = 50 m
Using Measurement Formulas,
Area of a Trapezoid = \(\dfrac{({base_1+base_2})}{2}\times height\)
= \(\dfrac{({200+100})}{2}×50\)
= 150 × 50
= 7500 m^{2}
Answer: The area of a trapezoidal park is 7500 m^{2}.
