Question

The length of the diagonals of a rhombus is 60 cm and 80 cm. Find the perimeter of the rhombus.

Answer 1

Answer:

The area of Rhombus is

$\frac{1}{2} 60 \times 80 = 240cm ^{2}$

The side of Rhombus is hypotenuse of semi diagonals

i.e.,

$side ^{2} = 30 ^{2} + 40 ^{2}$

side=50

The area can also be given as

×50×h=240

height=9.6cm
