The expression for perimeter of triangle is 6x + 21

Solution:

Given that,

Let the length of the bottom of the triangle be "x"

Another side is 7 more than 4 times the length of the bottom of the triangle

Length of another side = 7 + 4x

The last side is 14 more than the bottom of the triangle

Length of last side = 14 + x

The perimeter of triangle is given as:

Perimeter = sum length of length of all 3 sides of triangle

$Perimeter = x + 7 + 4x + x + 14\\\\Combine\ the\ like\ terms\\\\Perimeter = 6x + 7 + 14\\\\Add\ the\ constants\\\\Perimeter = 6x + 21$

Thus expression for perimeter of triangle is 6x + 21
