Reason (R): All sides of a square are equal.
Option: ___
Q2.
Assertion (A): The area of a rectangle is calculated by multiplying its length and breadth.
Reason (R): Area is the amount of space inside a closed figure.
Option: ___
Q3.
Assertion (A): Perimeter is measured in square units.
Reason (R): Perimeter is the length of the boundary.
Option: ___
Q4.
Assertion (A): A figure with the largest area will always have the largest perimeter.
Reason (R): Area and perimeter are always directly proportional.
Option: ___
Q5.
Assertion (A): The perimeter of a rectangle is 2 × (length + breadth).
Reason (R): A rectangle has opposite sides equal.
Option: ___
Q6.
Assertion (A): If all sides of a rectangle are equal, it becomes a square.
Reason (R): A square is a special type of rectangle.
Option: ___
Q7.
Assertion (A): A triangle has 3 sides and 3 vertices.
Reason (R): The perimeter of a triangle is the sum of the lengths of its sides.
Option: ___
Q8.
Assertion (A): The area of a square is side × side.
Reason (R): The side is the only measurement needed for calculating area in a square.
Option: ___
Q9.
Assertion (A): Area and perimeter of the same shape always increase together.
Reason (R): Bigger shapes always have both more area and more perimeter.
Option: ___
Q10.
Assertion (A): The unit of area is square centimetres or square metres.
Reason (R): Area represents surface coverage.
Option: ___
Q11.
Assertion (A): The perimeter of an equilateral triangle is 3 times one of its sides.
Reason (R): All sides in an equilateral triangle are equal.
Option: ___
Q12.
Assertion (A): A rectangle with length 5 cm and breadth 3 cm has area 15 cm².
Reason (R): Area of rectangle = length + breadth.
Option: ___
Q13.
Assertion (A): The boundary of a circle is called its perimeter.
Reason (R): The perimeter of a circle is also known as its circumference.
Option: ___
Q14.
Assertion (A): Irregular shapes can have perimeter but not area.
Reason (R): Area is defined only for regular shapes.
Option: ___
Q15.
Assertion (A): A square and a rectangle can have the same area but different perimeters.
Reason (R): The side lengths affect perimeter even when area is equal.
Option: ___
Q16.
Assertion (A): A rectangle of length 8 cm and breadth 2 cm has the same perimeter as a square of side 5 cm.
Reason (R): Perimeter of rectangle = 2 × (l + b), perimeter of square = 4 × side.
Option: ___
Q17.
Assertion (A): If the side of a square doubles, its area becomes four times.
Reason (R): Area of square is directly proportional to the square of its side.
Option: ___
Q18.
Assertion (A): To find the area of irregular figures, we can count square units inside them.
Reason (R): This method is known as approximation or unit square method.
Option: ___
Q19.
Assertion (A): All figures with the same perimeter have the same area.
Reason (R): Perimeter determines area directly.
Option: ___
Q20.
Assertion (A): When two shapes have equal area, their perimeters must also be equal.
Reason (R): Equal area always leads to equal perimeter.
Option: ___
