Area and Perimeter Aptitude Questions Online Test

Area and Perimeter are two important concepts in mathematics that are frequently tested in competitive exams such as entrance exams for colleges and universities, government job exams, and other competitive exams. In this article, we will discuss the formulas for finding the area and perimeter of some common 2-dimensional shapes and also provide tips to solve area and perimeter problems quickly and accurately.

Formulas for Area and Perimeter: Here are the formulas for finding the area and perimeter of some common 2-dimensional shapes:

Rectangle:

1. Area: width x height
2. Perimeter: 2 x (width + height)

Square:

1. Area: side x side
2. Perimeter: 4 x side

Triangle:

1. Area: (base x height) / 2
2. Perimeter: sum of all sides

Circle:

1. Area: π x (radius x radius)
2. Perimeter (circumference): 2 x π x radius

Parallelogram:

1. Area: base x height
2. Perimeter: 2 x (sum of the lengths of both parallel sides)

Trapezoid:

1. Area: ((base1 + base2) x height) / 2
2. Perimeter: sum of all sides

Note: In these formulas, width, height, base, radius, side, and the lengths of sides refer to the corresponding dimensions of the shape.

Tips for Solving Area and Perimeter Problems:

1. Practice: The more you practice solving area and perimeter problems, the more comfortable you will become with the formulas and the quicker you will be able to solve the problems.
