Rectangle (Rechteck) and Parallelogram (Parallelogramm)
This page covers the calculations for rectangles and parallelograms, demonstrating how to find their perimeters and areas.
For the rectangle, the dimensions are given as a = 6 cm and b = 4 cm. The formulas and calculations are as follows:
Umfang Rechteck Perimeter:
u = 2 • a+b
u = 2 • 6+4
u = 20 cm
Flächeninhalt Rechteck Area:
A = a • b
A = 6 • 4
A = 24 cm²
Highlight: The perimeter of a rectangle is calculated by adding all side lengths, while the area is found by multiplying length by width.
For the parallelogram, the dimensions are a = 6 cm, b = 5 cm, and ha height = 4 cm. The calculations are:
Parallelogramm Flächeninhalt Area:
A = a • ha
A = 6 • 4
A = 24 cm²
Formel Parallelogramm Flächeninhalt Perimeter:
u = 2 • a + 2 • b
u = 2 • 6 + 2 • 5
u = 22 cm
Vocabulary: ha represents the height of the parallelogram, which is perpendicular to the base.
Example: A parallelogram with base 6 cm, side 5 cm, and height 4 cm has a perimeter of 22 cm and an area of 24 cm².
