What is the perimeter of ABDE

Given:

Given that the graph of a triangle BDE.

The coordinates of the triangle are B(-2,3), D(2,6) and E(3,2)

We need to determine the perimeter of the triangle BDE.

Length of BD:

The length of BD can be determined by substituting the coordinates (-2,3) and (2,6) in the formula,

Length of DE:

Substituting the coordinates of D(2,6) and E(3,2) in the formula, we get;

Length of BE:

Substituting the coordinates of B(-2,3) and E(3,2) in the formula, we get;

Perimeter of ΔBDE:

The perimeter of triangle BDE can be determined by adding the lengths of BD, DE and BE.

Thus, we have;

Hence, the perimeter of ΔBDE is √17 + √26 + 5

Thus, Option A is the correct answer.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
