Question

two equal sides of a triangle is 4 meter less than the third side is the perimeter of the triangle is 70 metre find the length of its side​

Answer 1

Answer:

22m,22m,26m

Step-by-step explanation:

Let the sides be x-4,x-4,x

A/Q

(The sum of all sides=perimeter)

3x-8=70

3x=70+8

3x=78

x=78/3

x=26

Therefore,Length of triangle:

26-4=22

26-4=22

26

Answer 2

Answer:

Let,

3rd side = x

Hence,two sides of triangle is equal therefore it is

an isosceles triangle.

So, the equal sides = x-4 (each)

And, Perimeter = 70 m.

Therefore,

Side1st + Side2nd + Side3rd =

Perimeter of triangle

(x-4) + (x-4) + x = 70 m.

3x - 4 = 70 m.

x = 70+4/3

x =
