8/28/2023 0 Comments Picture of parallelogram![]() Let us see the applications of the perimeter of parallelogram formulas in this section. Now we know the sides of the parallelogram ('a' and 'b') and hence we can use the formula from the previous section to find its perimeter (P). Now, we will solve it for 'b' as we are not given the length of 'b'. We have got the relation between the sides and diagonals of the parallelogram. X 2 + y 2 = 2a 2 + 2b 2 - 2ab ( - cos ∠ADC + cos ∠ADC) We know that any two adjacent angles of a parallelogram (it is a property of parallelograms) are supplementary. Assume that the values of the side 'a', and the diagonals 'x' and 'y' are given but the value of 'b' is not given and we are asked to find the perimeter of the parallelogram.Īpplying the law of cosines for the triangle ABD,Īpplying the cosine rule for the triangle ADC, Let us consider a parallelogram with sides 'a' and 'b' and diagonals 'x' and 'y'. Perimeter of Parallelogram Base,Height,and Angle Perimeter of Parallelogram Formula With One Side and Diagonals Perimeter of Parallelogram Formula With Sides ![]() ![]() We will explore the concept with the help of a few solved examples for a better understanding of the concept. We shall also understand the applications of the perimeter of parallelogram formulas. In this article, we will learn how to find the perimeter of a parallelogram using some formulas.
