Question

the area of rhombus is 216 cm square. If its perimeter is 48 cm find its altitude ?

Answer 1

Hello !!!!!!!!!!

the area of each right angled triangle is

216\4 = 54

1/2 x 1/2 x 9 = 54

54\9 = 24 cm

OR ( there are two ways to find the answer )

Area of rhombus =(1/2)×d1×d2

216=(1/2)×18×d2

216/9=d2

24=d2

Length other diagonal = 24 cm
