Area of a triangle is the region covered by its three sides in a plane. Area of a triangle is equal to half of product of its base and height. Find the area using heron's formulas and SAS condition, with examples at BYJU'S.
i.e. We can define the product {eq}AB {/eq} provided the number of columns of {eq}A {/eq} is equal to the number of rows of {eq}B {/eq}. In this case, the dimension of the resultant matrix is {eq}m\times n {/eq}. If we consider the entries of the matrices as, $...
