Question

Find the base of the rhombus if its altitude is 8 cm and the area is 72 cm square. Also find its perimeter.....

Answer 1

area  of rhombus = base * height

here, 72 =  8*base

72/8 = base

9 = base 

base is 9cm 

then 

perimeter = 4*side

perimeter = 4*9

perimeter = 32cm

i hope this will help you

Answer 2

a=l×b
72=8×b
72/8=b
b=9cm


p=2 (9cm+8cm)
p=2×17cm
p=34cm.
