By the Pythagorean theorem, we find that each of the sides of the rhombus is √([7.5)² + (4)²] = √[56.25 + 16] = √72.25 = 8.5 cm. The perimeter of the rhombus is four times the length of one side: 34 cm.

Remember the formula for finding the perimeter of a triangle. For a triangle with sides a, b and c, the perimeter P is defined as: P = a + b + c. What this formula means in simpler terms is that to find the perimeter of a triangle, you just add together the lengths of each of its 3 sides.

Perimeter of a Semicircle The formula for a circle's circumference, C, is C = 2 * pi * r, where r is, again, the circle's radius. A semicircle is half a circle, however, so we'll need to divide the formula for perimeter by two just like we did the formula for area. The perimeter P = pi * r. But wait!

Correct answer: The length of a diagonal of a square is times the length of a side; since the rhombus has perimeter 80, each side measures one fourth of this, or 20, and diagonal has length .

Since all sides of a square are equal, we only need one side to find its perimeter. The perimeter of the given square is: a + a + a + a = 4 a units. Hence, the formula of the perimeter of a square = 4 × (length of any one side).
