Question

calculate the perimeter of a rhombus with diagonals 6 m and 8 m long. type only the number value of your answer to the nearest whole number.

Explanation:

Step1: Find half-diagonals

Half of 6 m: $\frac{6}{2}=3$ m; Half of 8 m: $\frac{8}{2}=4$ m

Step2: Calculate side length

Use Pythagorean theorem: $s=\sqrt{3^2+4^2}=\sqrt{9+16}=\sqrt{25}=5$ m

Step3: Compute perimeter

Perimeter = $4\times s = 4\times5=20$ m

Answer:
