Answer 1

75 cm

Explanation:

Given:

Perimeter of the triangular yield sign = 225 cm

Side lengths = x, x and x

Required:

Length of each side

SOLUTION:

Perimeter of the triangular yield sign = sum of all sides of the triangular yield sign

225 cm = x + x + x

Solve for x

225 = 3x

Divide both sides by 3

225/3 = 3x/3

75 = x

x = 75

The length big each side is 75 cm
