Area And Circumference Formula Of Trapezoidal
Trapezoid there are 3 kinds, including:
1. Trapezoid Any
An arbitrary trapezoid has only parallel sides.
2. Trapezium Equal Legs
Characteristics:
3. Trapezoidal Bracket
Trapezoidal bracket is a trapezoid whose two corners are elbow.
Answer:
Number of parallel sides = 12cm + 18cm = 30cm
Height = 10cm
Trapezoidal Area = 1/2 (number of parallel sides) x height
Trapezoidal Area = 1/2 (30cm) x 10cm
Trapezoidal Area = 1/2 x 300cm2
Trapezoidal Area = 150cm2
So the trapezoidal area is 150cm2
Answer:
AB = 15cm
BC = 10cm
CD = 27cm
AD = 10cm
Circumference Trapezoidal = The length of the four sides
Circumference Trapezoidal = AB + BC + CD + AD
Circumference Trapezoidal = 15cm + 10cm + 27cm + 10cm
Circumference Trapezoidal = 52cm
So the circumference of the trapezoid is 52cm.

An arbitrary trapezoid has only parallel sides.
2. Trapezium Equal Legs
Characteristics:
- Has one pair of parallel sides.
- Has one side pairs of the same length (trapezoidal foot AD = BC).
- Has two pairs of angles equal ∠A = ∠B = x and ∠D = ∠C.
3. Trapezoidal Bracket
Trapezoidal bracket is a trapezoid whose two corners are elbow.
Formula of Trapezoidal Area
Trapezoidal Area = 1/2 (number of parallel sides) x height
Example Question of Trapezoidal Area
Please determine the trapezoidal area with parallel sides of 12cm and 18cm each and 10cm in height!Answer:
Number of parallel sides = 12cm + 18cm = 30cm
Height = 10cm
Trapezoidal Area = 1/2 (number of parallel sides) x height
Trapezoidal Area = 1/2 (30cm) x 10cm
Trapezoidal Area = 1/2 x 300cm2
Trapezoidal Area = 150cm2
So the trapezoidal area is 150cm2
Formula of Circumference Trapezoidal
Circumference Trapezoidal = The length of the four sides
Example of Circumference Trapezoidal
What is the trapezoidal circumference below!Answer:
AB = 15cm
BC = 10cm
CD = 27cm
AD = 10cm
Circumference Trapezoidal = The length of the four sides
Circumference Trapezoidal = AB + BC + CD + AD
Circumference Trapezoidal = 15cm + 10cm + 27cm + 10cm
Circumference Trapezoidal = 52cm
So the circumference of the trapezoid is 52cm.
