Question

What is the perimeter of a rhombus-shaped street sign with a 35-cm side?

A. 280 cm
B. 140 cm
C. 1,225 cm
D. 70 cm

Answer 1

A rhombus has a total of 4 sides. All sides are equal. The formula of getting the perimeter of a rhombus is:
Perimeter = 4 * S
Perimeter = 4 * 35 cm
Perimeter = 140 cm.

So the perimeter of a rhombus-shaped street sign that has a 35-cm side is equal to (B) 140 cm.
