Question

find the altitude of the rhombus whose area is 30 cm^2 and permeter is 24cm

Answer 1

since it is a rombus all sides will be equal
perimeter = 4 a =24
a = 24/4
a = 6cm

area of rhombus = base x height 
   (area = 30cm^2
    base = 6)
area = 30 = 6 x h
          h = 30/6
          h = 5

altitude of rhombus = 5cm

Answer 2

Given perimeter = 24cm.

We know that perimeter of the rhombus P = 4 * S.

Then the side will be S = P/4.

                                        =24/4

                                        = 6.


Given Area = 30cm^2.

The area of the rhombus = b * h

        30 = 6 * h

         30/6 = h

          h = 5.


Therefore, the altitude of the rhombus = 5cm.


Hope this helps!
