Perimeter Area and Volume Questions
On this page we will be discussing about heights and distance questions that are asked in placement exams. Perimeter and Area is one of the most important topics related to which questions are asked in placement.
Perimeter
Perimeter is the distance around the closed space of a shape or a closed curve, such as a circle. The formula for calculating perimeters varies on the kind of shape.
Area
Area can be discussed as the size of space in the interiors of the shape. Area is often measured in square units. Similarly, the formula for calculating area varies on the kind of shape.
Volume
Volume is calculated only for solid 3D shapes, such as cylinder, cubes, spheres and more. The amount of space or mass covered in the object of any shape and size is known as its volume.
Formulas
Rectangle
- Area = Length * Width
- Perimeter = 2 [Lengths + Widths]
Triangle
- Area = 1/2 * base * height
- Perimeter = a + b + c (add the length of the three sides)
- Area using Heron’s formula = S = \frac{a + b + c}{2}
then, Area = \sqrt{S(S – a)(S – b)(S – c)}

Cuboid
- Volume = Length * Width * Height
- Surface = 2lw + 2lh + 2wh
- Curved Surface Area = 2h(l + b)
Cylinder
- Volume = \pi r^2\times \text{ height }
- Surface area = 2\pi rh + 2\pi r^2
- Curved Surface Area = 2\pi rh
Sphere
- Volume = \frac{4}{3}\pi r^3
- Surface = 4\pi r^2
