Question

Two equal sides of a trangleand each 5meters less than the third side. If theperimeter of the triangle is 55meters,find the lengths of its side

Answer 1

This is the answer of your Q

Answer 2

let the length of the third side be x m

length of each of the two equal sides = x-5 m

perimeter of the triangle=55m

according to the question:

=> x+(x-5)+(x-5)=55

=> x+x-5+x-5=55

=> 3x-10=55

=> 3x=65

=> x=65/3

=> x= 21.67

length of third side=21.67m

length of each of two equal sides=21.67-5
                                                        = 16.67 m
