Question

area of rhombus is 84cmsquare if its perimeter is 40 cm find its altitude

Answer 1

ar=84cm
p=40cm
4*sides=40
s=40/4
=10cm
ar. of rhombus=84cm2
b*h=84
h=84/10
h=8.4cm

Answer 2

Heya,
Here is your answer.
》》》》》》》》》

☆ Perimeter of Rhombus = 40 cm
Since, all sides if RHOMBUS are equal,
each side = 40/4 = 10 cm

☆ Area = side×altitude (a)
10×a = 84 cm
a = 84/10
a = 8.4

☆ Altitude = 8.4

Hope it helps.
