Sample Questions – Is every rectangle a rhombus
Question 1. Calculate the area of a rectangular frame, which has 6 inches in length and is 3 inches wide.
Solution:
Since, we know,
Area of a Rectangle = (Length × Width) square units.
Substituting the values, we obtain,
the area of rectangular frame = 6 × 3 = 18 square inches
Question 2. Find the length of diagonal of a rectangle which has length as 12 cm and width, 8 cm respectively.
Solution:
We know,
Diagonal Length,
D = [Tex]\sqrt{ L^2+W^2}[/Tex]
⇒ D = [Tex]\sqrt{12^2+8^2}[/Tex]
⇒ D = [Tex]\sqrt{144 + 64}[/Tex]
⇒ D = √208
⇒ D = 4√3
Question 3. Find the area of a rhombus with the two diagonal lengths d1 and d2 to be 6cm and 12 cm, respectively.
Solution:
We have,
Diagonal d1 = 6cm
Diagonal d2= 12 cm
Area of the rhombus is given by,
A = [Tex] \frac{(d_1 \times d_2)}{2}[/Tex] sq. units
A = [Tex]\frac{( 6 \times 12)}{2}[/Tex]
A = [Tex]\frac{72}{2}[/Tex]
A = 36 cm2
Therefore, the area of rhombus = 36 cm2.
Question 4. Difference between Rhombus and Rectangle?
Solution:
Property | Rhombus | Rectangle |
Sides | Equal sides. | Opposite sides are equal. |
Diagonals | The diagonals bisect each other at 90°. Diagonals make right angles at the center. | The diagonals bisect each other at different angles. One angle is an obtuse angle and the other one is an acute angle. Diagonals make different angles at the center – an obtuse angle and an acute angle. |
Angles | Opposite angles are equal. Adjacent angles add up to 180°. | Opposite and adjacent angles are equal. An angle formed by the adjacent sides of a rectangle is 90°. |
Is every rectangle a rhombus?
Is every rectangle a rhombus? Rectangle is a two-dimensional geometrical figure depicted by four sides and four corners. A rectangle contains sides such that the length of the opposite sides is equal and these sides are parallel to each other. The sides sharing a corner from adjacent sides with an angle of 90° between them. Therefore, there are four right angles in the rectangle.
