Question

the area of a rhombus is 42 cm if its perimeter is 24 m find its altitude.

Answer 1

hello frnd!!

here's ur answer...

we know that all side in rhombus have equal length.

perimeter of the rhombus=24cm

side×4=24cm

side=24/4

side=6cm

hence, length of the side of rhombus is 6cm.

area of the rhombus=42cm²

here, side of the rhombus be the base.

b×h=42cm²

6×h=42cm²

h=42/6

h=7cm

thus, the altitude of rhombus is 7cm.

hope this helps...

Answer 2

Given that perimeter of the rhombus = 24m.

We know that perimeter of the rhombus = 4 * side.

24 = 4 * side

side = 6cm.


Given that Area of rhombus 42cm.

We know that Area of rhombus = Base * Altitude

   42 = 6 * Altitude

Altitude = 42/6

              = 7cm.


Therefore the altitude of the rhombus = 7cm.


Hope this helps!
