Question: what is the formula for finding the area of a rhombus?
Answer: Area of rhombus=1/2 *product of diagonals=1/2*16*12=96 sq.cm. How can I find area of rhombus if the length of a diagonal and perimeter is given? You can't find the area with the information you have. Either you need the length of each diagonal (which you don't have), or you need the base and the height.
