Quadrilaterals (Rhombuses): แบบฝึกหัด

Which of the following describes the opposite sides of a rhombus?

Which statement correctly describes the relationship between squares, rectangles, and rhombuses?

If one side of a rhombus measures \(7.5\text{ cm}\), what is its perimeter?

Which of the following statements is true for a rhombus?

The perimeter of a rhombus is \(48\text{ cm}\). What is the length of each side?

A rhombus has a side length of \(8\text{ cm}\). What is the total length of its four sides?

Consider a rhombus ABCD and related geometric shapes:

(a) The rhombus ABCD has a side length of \(14\text{ cm}\). Find its perimeter.

(b) A rectangle is constructed such that its width is equal to the side length of the rhombus, and its length is \(5\text{ cm}\) longer than its width. Find the perimeter and the area of this rectangle.

(c) If a square has the same perimeter as the rectangle found in part (b), determine the side length of the square and calculate its area.
