Find the altitude of rhombus whose area is 420cm(sq) and the perimerter is 140 cm..
We know that allsides of Rhombus are equal ,there fore let the side be ' x '
so,
Perimeter =sum of all sides= x+x+x+x =140
4x=140
x=140/4
x=35
Area of rhombus is i. 1/2 x d1 x d2 O r ii. base x height
BxH = 420
we know that B(base)=35
BxH=420
H=420/35
H=12
ALTITUDE = 12 cm
