Question

the perimeter of the Rhombus is 260 cm and the height is 10 centimetre if one diagonal is 0.25 metre find length of other diagonal in metre

Answer 1

since all the sides of rhombus are equal
therefore length of 1 side = 260/4= 65
area of rhombus = product of diagonals
length of a side* height = 65cm * 10 cm
= 650cm²
if one diagonal is 0.25 m (25 cm)
therefore other diagonal =
area / diagonal
= 650 cm² / 25 cm²
= 26 cm
