the area of a rhombus is equal to the area of a rectangle whose length is 20 cm and the breadth is 10 cm. if one of the diagonals is 32 cm what is the length of other diagonal?
divide(multiply(rectangle_area(20, 10), const_2), 32)
area of rectangle = 20 x 10 = 200 cm â ² let ' l ' the length of other diagonal = 0.5 x 32 xl = 200 which gives x = 12.5 cm answer : b
