Answer 1

MCQs of Perimeter and Area:-

What is Perimeter?

a) total length of sides of a plane.

b) length of one side of a plane.

c) length of 2 sides of a plane.

d) area covered by the plane.

Ans. a) total length of sides of a plane, because perimeter is the sum of length of all the sides off a plane.

What is the Perimeter of a square?

a) side × side.

b) 2 × side.

c) side.

d) 4 × side.

Ans. d) 4 × side, as perimeter of square is side + side + side + side, so by simplifying we get, 4 × side.

What is the Perimeter of a Rectangle?

a) Length + Length

b) 2 × (Length + Breadth)

c) Lenght + Breadth

d) Breadth × 2 + Length

Ans. b) 2 × (Length + Breadth), as Perimeter of Rectangle is Length + Length + Breadth + Breadth.

What is the Perimeter of a Triangle?

a) a + b + c

b) a + side

c) side × 1/2

d) side × a + 2/3

Ans. a) a + b + c, as sum of all three sides of triangle, a, b and c, is its perimeter.

What is the Circumference of a Circle?

a) 2 × π × r

b) πr

c) 1/2 πr

d) 3 × πr

Ans. a) 2πr, is the circumference or perimeter of a circle.

What is Area?

a) space occupied by any 3d objects.

b) space occupied by 4d objects.

c) space occupied by any plane.

d) none of the above.

Ans. c) space occupied by any plane 2-Dimensional figure is the area of it.

What is the Area of a Rectangle?

a) 2 × (a + b)

b) 2 × base/height

c) 2 × Length

d) Length × Breadth

Ans. d) Length × Breadth, as its the formula to find the area of any rectangle.

What is the Area of a Square?

a) side × side

b) side + 1/side

c) side + 2base

d) base × base

Ans. a) side × side, as it is the formula to find the area of any square by its only one side.

What is the Area of a Right Triangle?

a) 2 × (base + hypostenuse)

b) side × side

c) $\frac{1}{2} base \times height$

d) a + b + c

Ans. c) $\frac{1}{2} base \times height$, as it is the formula to find area of a right triangle.

What is the Area of a Circle?

a) $\pi \times {r}^{2}$

b) π × π

c) 2 π r

d) r + 1/2 π

Ans. a) $\pi \times {r}^{2}$, as it is the formula to find area of any circle using its radius, r.

What is the Area of a Parallelogram?

a) base + height

b) 2 × base

c) 1/2 × height

d) base × height

Ans. d) base × height, as it is the formula to find area of a parallelogram using its base and height.
