Since a rhombus has four (4) equal sides, the perimeter of this polygon is equal to D. 4√(a² + b²).
How to calculate the perimeter of this polygon?
By critically observing the polygon, we can logically deduce that it's a rhombus and it has 4 equal sides.
By applying the distance formula, the side lengths are given by:
S = √(a² + b²)
Since a rhombus has four (4) equal sides, the perimeter is given by this equation:
P = 4S
P = 4√(a² + b²).
