Question

The perimeter of a rhombus is 45 cm. If its height is 8 cm, calculate its area

​

Answer 1

Answer:.

Step-by-step explanation: as we know all the sides of rhombus are equal

this implies that

perimeter=4*side

45=4*side

side=45/4

     area = base * height

     here, height = 8 cm

area = 8*45/4

      = 90cm^2

 

   

Answer 2

Answer:

Perimeter= 45 cm

let the side= b

4b=45/4

b=45/4

b is also the base of rohmbus

area of rohmbus= base*height

45/4*8

45*2

90cm^2
