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.

PerimeterPerimeter 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.

AreaArea 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.

VolumeVolume 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)}
