Question

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

Answer 1

perimeter of Rhombus = 260

4a =260
a=65


Area of Rhombus = Base × Height


Base(side) = 65
Height =10cm

A =65×10 =650sq cm

We know that

1/2 × d1×d2 = Area of Rhombus


A= 650
d1= .25 m= 25cm
d2=?


d2= (A×2)/d1
d2=( 650×2)/25

d2= 1300/25=52 cm

So length of other diagonal is 52cm.
