Question

two equal sides of a triangle are 5m less than twice the side. if rhe perimeter of the triangle is 55m. find the length of its sides.​

Answer 1

Let the third side = x

Then the equal sides = 2x - 5

Perimeter = 55m

So,

x + x + 2x - 5 = 55

3x - 5 = 55

3x = 55 + 5

3x = 60

x = 20m

________________________________

$\mathfrak{All\:the\:sides\:are:-}$

x = 20 m

x = 20 m

2x - 5 = 40 - 5 = 35 m

Sides - 20m , 20m , 35m
