If A is any square matrix of order 2 x 2 such that |A| = -7, then the value of |adj. A| is

A square matrix is a matrix with an equal number of rows and columns. The order of a square matrix refers to its size, represented as “n x n,” where “n” is the number of rows (or columns). Examples include 2×2, 3×3, 4×4 matrices, and so on.

Class 12 Maths Chapter 4 focuses on Determinants. It covers properties of determinants such as addition subtraction multiplication of determinants along with cofactor expansion method. The chapter also includes applications like finding the area of a triangle solving systems of linear equations using Cramer’s rule and understanding the inverse of a matrix. This is crucial for CBSE Exam 2024-25.
