Geometry is a fascinating branch of mathematics that deals with shapes, sizes, and positions of objects. One of the fundamental concepts in geometry is the area of a shape, which refers to the amount of space inside a two-dimensional object. In this article, we'll explore the areas of trapezoids, rhombuses, and kites, and provide a worksheet to help you practice your skills. Let's dive in!

Trapezoids

A trapezoid is a four-sided shape with two parallel sides, called bases, and two non-parallel sides, called legs. To find the area of a trapezoid, we use the formula:

Area = ((base 1 + base 2) / 2) x height

where base 1 and base 2 are the lengths of the parallel sides, and height is the perpendicular distance between the bases. Let's try an example:

Example: Find the area of a trapezoid with base 1 = 5 cm, base 2 = 9 cm, and height = 8 cm.

Solution: Using the formula, we get:

Area = ((5 + 9) / 2) x 8 = 56 cm²

Therefore, the area of the trapezoid is 56 cm².

Rhombuses

A rhombus is a four-sided shape with all sides of equal length. To find the area of a rhombus, we use the formula:

Area = (diagonal 1 x diagonal 2) / 2

where diagonal 1 and diagonal 2 are the lengths of the diagonals of the rhombus. Let's try an example:

Example: Find the area of a rhombus with diagonal 1 = 6 cm and diagonal 2 = 8 cm.

Solution: Using the formula, we get:

Area = (6 x 8) / 2 = 24 cm²

Therefore, the area of the rhombus is 24 cm².

Kites

A kite is a four-sided shape with two pairs of adjacent sides that are of equal length. To find the area of a kite, we use the formula:

Area = (diagonal 1 x diagonal 2) / 2

where diagonal 1 and diagonal 2 are the lengths of the diagonals of the kite. Let's try an example:

Example: Find the area of a kite with diagonal 1 = 7 cm and diagonal 2 = 10 cm.

Solution: Using the formula, we get:

Area = (7 x 10) / 2 = 35 cm²

Therefore, the area of the kite is 35 cm².
